I'm building an embedded Perl application with XS modules.

I build perl 5.8.1 (problem exists in 5.8.0 also but I don't think I 
reported it) on Win32 (XP) platform with win32/Makefile patched as under 
"Makefile.patch" at the end of this message.

My build fails (in ext - unresolved symbol - the interpreter, if I recall 
correctly) unless I patch regcomp.c and regexec.c as follows:
