Well,
with the help of Tatsuo I found the problem is in backend/regex/regcomp.c
I'll look for more details and probably could make a fix.
quick question: is there in sources locale-aware strncmp function
or I need to write myself ?
As for the compiler option I think we should'nt use any
"-funsigned-chars" like options !
Regards,
Oleg
