First, the problem. Sample program:
#include <ctype.h>
int main(void) { return 0; }
% g++ -c bug.cxx

error: 'regex_t' has not been declared
Normally, lc_core.h #includes reg_types.h, which has the regex_t typedef, and
all is well. Here, however, it pulls in the fixincluded version of reg_types.h,
which typedefs __regex_t, not regex_t.
This is not a problem for [the fixincluded] regex.h, since right after it
#includes reg_types.h, it typedefs __regex_t to regex_t. Anything else that
uses reg_types.h expecting to get regex_t, however, is left in the lurch.

Summary: Fixincluded header defines __regex_t, other header needs
regex_t
