AIX compile fix for repo-config.c

AIX 5 has a /usr/include/regex.h containing this code:

 #ifdef  _NO_PROTO
 extern  char    *regex();
 extern  char    *regcmp();
 #else /* _NO_PROTO */
 extern  char    *regex(const char *, const char *, ...);
 extern  char    *regcmp(const char *, ...);
 #endif  /* _NO_PROTO */

This means that repo-config.c is trying to redefine the `regex' symbol.
Here is a simple patch that just uses `regexp' as the symbol name instead.
