in the OS4 SDK. Otherwise "struct timeval" will not be defined at the time the <net/if.h> of the netincludes will be included by <proto/bsdsocket.h>. - The strftime() hook function had the locale and character parameters switched, which made 'setlocale(LC_ALL,""); strftime(..);' unusable. Fixed. - fchown() and chown() now accept owner and group ID values of -1, which indicate that the respective information should not be changed. - The OS4 library build now includes the crtbegin.o and crtend.o object files in the libc.a library, which solves a problem with the thread-safe shared library support code. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@15090 87f5fb63-7c3d-0410-a384-fd976d0f7a62
