Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

If there was an error, make the exit status reflect this even if -quit
caused the exit. Formerly, -quit always caused exit(0).
GNU find does the same.

As per POSIX, the -exec ... {} + primary always returns true, but a non-zero
exit status causes find to return a non-zero exit status itself. GNU does
the same, and also for -execdir ... {} +.
It does not make much sense to return false from the primary only when the
child process happens to be run.
The behaviour for -exec/-execdir ... ; remains unchanged: the primary
returns true or false depending on the exit status, and find's exit status
is unaffected.

fts_read() leaves errno unchanged on EOF and sets it on error, so set errno
to 0 before calling it. Also, don't trust finish_execplus() to leave errno
unchanged.

This avoids unexpected partial processing when a find command uses both
-quit and -exec ... +.
GNU find does the same.

fts(3) detects directories even in FTS_NOSTAT mode (so it can descend into
them).
No functional change is intended, but find commands that use -type d but no
primaries that still require stat/lstat calls make considerably fewer system
calls.

* Do not match symlinks that are followed because of -H or -L. This is
explicitly documented in GNU find's info file and is like -type l.
* Fix matching symlinks in subdirectories when fts changes directories.
Also, avoid some readlink() calls on files that are obviously not symlinks
(because of fts(3) restrictions, not all of them).

The code did not take into account that readlink() does not add a
terminating '\0', and therefore did not work reliably.
As before, symlinks of length PATH_MAX or more are not handled correctly.
(These can only be created on other operating systems.)

Formerly, a command like find dir1/dir2 -delete would delete everything
under dir1/dir2 but not dir1/dir2 itself.
When -L is not specified and "." can be opened, the fts(3) code underlying
find(1) is careful to avoid following symlinks or being dropped in different
locations by moving the directory fts is currently traversing. If a
problematic concurrent modification is detected, fts will not enter the
directory or abort. Files found in the search are returned via the current
working directory and a pathname not containing a slash.
For paranoia, find(1) verifies this when -delete is used. However, it is too
paranoid about the root of the traversal. It is already assumed that the
initial pathname does not refer to directories or symlinks that might be
replaced by untrusted users; otherwise, the whole traversal would be unsafe.
Therefore, it is not necessary to do the check for fts_level ==
FTS_ROOTLEVEL.
Deleting the pathnames given as arguments can be prevented without error
messages using -mindepth 1 or by changing directory and passing "." as
argument to find. This works in the old as well as the new version of find.

This compiler flag enforces that that people either mark variables
static or use an external declarations for the variable, similar to how
-Wmissing-prototypes works for functions.
Due to the fact that Yacc/Lex generate code that cannot trivially be
changed to not warn because of this (lots of yy* variables), add a
NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this
specific compiler warning.

When comparing to the timestamp of a given file using -newer, -Xnewer and
-newerXY (where X and Y are one of m, c, a, B), include nanoseconds in the
comparison.
The primaries that compare a timestamp of a file to a given value (-Xmin,
-Xtime, -newerXt) continue to compare times in whole seconds.
Note that the default value 0 of vfs.timestamp_precision almost always
causes the nanoseconds part to be 0. However, touch -d can set a timestamp
to the microsecond regardless of that sysctl.

fts(3) can run (albeit more slowly and imposing the {PATH_MAX} limit) when
the current directory cannot be opened. Therefore, do not make a failure to
open the current directory (for returning to it later in -exec) fatal.
If -execdir or -delete are used, the expectation is that fts(3) will use
chdir to avoid race conditions (except for -execdir with -L). Do not break
this expectation any more than it already is by still failing if the current
directory cannot be opened.

This is inefficient but ensures that -execdir ... {} + does not mix files
from different directories in one invocation; the command could not access
some files. Files from the same directory should really be handled in one
invocation but this is somewhat more complicated.

As of FreeBSD 6, devices can only be opened through devfs. These device
nodes don't have major and minor numbers anymore. The st_rdev field in
struct stat is simply based a copy of st_ino.
Simply display device numbers as hexadecimal, using "%#jx". This is
allowed by POSIX, since it explicitly states things like the following
(example taken from ls(1)):
"If the file is a character special or block special file, the
size of the file may be replaced with implementation-defined
information associated with the device in question."
This makes the output of these commands more compact. For example, ls(1)
now uses approximately four columns less. While there, simplify the
column length calculation from ls(1) by calling snprintf() with a NULL
buffer.
Don't be afraid; if needed one can still obtain individual major/minor
numbers using stat(1).

Ignoring the parameter with the unknown options is unlikely to be what was
intended.
Example:
find -n .
Note that things like
find -n
already caused an exit, equivalent to "find" by itself.
