*	libc: Always use our own copy of sys_errlist and sys_nerr (.so only).	jilles	2013-08-31	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This ensures strerror() and friends continue to work correctly even if a (non-PIE) executable linked against an older libc imports sys_errlist (which causes sys_errlist to refer to the executable's copy with a size fixed when that executable was linked). The executable's use of sys_errlist remains broken because it uses the current value of sys_nerr and may access past the bounds of the array. Different from the message "Using sys_errlist from executables is not ABI-stable" on freebsd-arch, this change does not affect the static library. There seems no reason to prevent overriding the error messages in the static library.
*	Make the %V{is} extension handle a NULL pointer like %s does: output "(null)"	phk	2006-01-25	1	-0/+65
	Add %M{essage} extension which prints an errno value as the corresponding string if possible or numerically otherwise. It is not currently possible to do the syslog(3) like %m extension because errno would need to get capatured on entry to the first function in the printf family, so %M requires you to supply errno as an argument. Add %Q{uote} extension which will print a string in double quotes with appropriate back-slash escapes (only) if necessary.
