I am working on a cygwin port from Linux. Straight forward, but one thing
puzzels me. Why is the regcomp call diffrent. I have to use this pice of
code to make it work on both platforms:

#ifdef cygwin
    regex_t *re;
#else
    regex_t a, *re;
    re = &a;
#endif

    i = regcomp(re, filter, REG_EXTENDED);

If I use a preallocated buffer in Cygwin i get an i = 269335288 = random.
Program gets unstable after the call. If I use a pointer it works.

On the linux box (Suse 7.0) I get a segmentation violation trying to run
with a pointer. Will run fine with a preallocated buffer. They are oposite
in behavior. What do I miss?
