Subject: libcdecl: Mark pthread_once as weak when needed.
X-Git-Tag: v1.3~1
X-Git-Url: https://git.draconx.ca/gitweb/cdecl99.git/commitdiff_plain/e858f29097fa175c861339a15c5e1f04ac511036

libcdecl: Mark pthread_once as weak when needed.

When the "lock" module was removed we forgot to add pthread_once to
the list of pthreads symbols marked weak, leading to build failures
on systems which don't provide this symbol in libc.
