See the Info reference manual for the DJGPP library (from the DOS
prompt, type "info libc alpha regcomp").  See, it explicitly says to
use these two headers:

    #include <sys/types.h>
    #include <regex.h>

In other words, that program is buggy: it's not portable to any
platform except GNU/Linux.
