Modified Files:
        src/lib/libc/regex: regerror.c

Log Message:
regerror(3): Allow null errbuf if errbuf_size is zero.

The man page says:

   If errbuf_size is 0, errbuf is ignored but the return value is still
   correct.

POSIX says:

   If errbuf_size is 0, regerror() shall ignore the errbuf argument,
   and return the size of the buffer needed to hold the generated
   string.
