2000-01-25 Andreas Schwab <schwab@suse.de> * posix/testfnm.c: Add new test case. Use FNM_PATHNAME instead of FNM_FILE_NAME consistently. * posix/fnmatch.c: Define STRCOLL appropriately for the loop definition. * posix/fnmatch_loop.c: Undefine STRCOLL. * sysdeps/unix/sysv/linux/i386/fxstat.c: Correct code to handle kernels with stat64 support. * sysdeps/unix/sysv/linux/i386/lxstat.c: Likewise * sysdeps/unix/sysv/linux/i386/xstat.c: Likewise. Patch by SL Baur <steve@xemacs.org>.
