I know, this is a kludge, - but Visual C++ 2.1 seems to require it (why, I have no idea. It - has no trouble with the #line directives in getdate in CVS 1.6). - -Sat Nov 18 16:20:37 1995 Karl Fogel <kfogel@floss.cyclic.com> - - * rename.c: same. - - * mkdir.c: Use new macro `existence_error', instead of comparing - errno to ENOENT directly. - - * system.h (existence_error): new macro, tries to portably ask if - errno represents a file-not-exist error. - -Fri Nov 17 20:08:58 1995 Karl Fogel <kfogel@floss.cyclic.com> - - * system.h (NEED_DECOY_PERMISSIONS): moved this section to where - it belongs, duh. - - * getdate.c: if STDC_HEADERS, then just include <stdlib.h> instead - of declaring malloc() and realloc() to be char *. - - * system.h: ifdef NEED_DECOY_PERMISSIONS, then define the S_I* - permission masks for USR, GRP, and OTH in terms of the simpler - OS/2 masks. - -Wed Nov 15 15:36:03 1995 Karl Fogel <kfogel@floss.cyclic.com> - - * system.h: ifdef USE_OWN_TCPIP_H, then include "tcpip.h". Only - OS/2 does this right now. - -Tue Nov 14 18:44:57 1995 Greg A. Woods <woods@most.weird.com> - - * getdate.c: OK, this one is from SunOS-4.1 yacc and may be more - portable -- at least it compiles silently here! ;-) - -Mon Nov 13 03:53:45 1995 Karl Fogel <kfogel@floss.cyclic.com> - - * fnmatch.c: conform to 80 column standard (yes, I'm a pedant). - -Wed Nov 8 11:10:59 1995 Karl Fogel <kfogel@floss.cyclic.com> - - * system.h (STAT_MACROS): ifdef S_IFMT, then use it as before; but - if it's not defined, then just do a single mask and assume - acceptance any of non-zero result. Norbert, I trust you'll let me - know if this is unsatisfactory. :-) - Ifdef HAVE_SYS_UTIME_H, then include <sys/utime.h>. Only OS/2 - defines this right now. - -Wed Nov 8 13:18:51 1995 Norbert Kiesel <nk@col.sw-ley.de> - - * valloc.c: omit malloc declaration (it's already in system.h - which is included and conflicts with <stdlib.h> on some - systems). - -Tue Nov 7 19:38:48 1995 Norbert Kiesel <nk@col.sw-ley.de> - - * system.h (STAT_MACROS_BROKEN): undo previous change, because - else all regular files will be identified as links (the mask for - links is S_IFREG|S_IFCHR). - -Mon Nov 6 19:20:56 1995 Karl Fogel <kfogel@floss.cyclic.com> - - * system.h (STAT_MACROS_BROKEN): in defining the S_IF* macros, - don't fold to 1 or 0 by first masking with S_IFMT; not all - systems have that macro, and anyway it's only necessary that we - return non-zero. - -Fri Oct 27 13:43:35 1995 Karl Fogel <kfogel@floss.cyclic.com> - - * save-cwd.c: use __PROTO instead of __P (see below). - - * getline.h (__PROTO): same as below. - - * save-cwd.h (__PROTO): replaces __P. New name, so don't ask if - already defined. The conflict was that OS/2 w/ IBM C/C++ uses - `__P' for something else, in <ctype.h> of all places. - - * system.h: do nothing about alloca ifdef ALLOCA_IN_STDLIB (see - ../src/ChangeLog). - -Tue Oct 24 13:01:25 1995 Norbert Kiesel <nk@col.sw-ley.de> - - * wait.h: include sys/resource.h if available.

On the few -** remaining systems that neither statement is true, _POSIX_PATH_MAX -** is defined. -** -** So: -** 1. If PATH_MAX is defined just use it. -** 2. If MAXPATHLEN is defined but not PATH_MAX, then define -** PATH_MAX in terms of MAXPATHLEN. -** 3. If neither is defined, include limits.h and check for -** PATH_MAX again. -** 3.1 If we now have PATHSIZE, define PATH_MAX in terms of that. -** and ignore the rest. Since _POSIX_PATH_MAX (checked for -** next) is the *most* restrictive (smallest) value, if we -** trust _POSIX_PATH_MAX, several of our buffers are too small. -** 4. If PATH_MAX is still not defined but _POSIX_PATH_MAX is, -** then define PATH_MAX in terms of _POSIX_PATH_MAX. -** 5. And if even _POSIX_PATH_MAX doesn't exist just put in -** a reasonable value. -** *. All in all, this is an excellent argument for using pathconf() -** when at all possible.
