It also breaks building on darwin versions before 11. (I'm on darwin 9
currently, but I'm sure it would happen on darwin 10, too; strndup() wasn't
added to the darwin Libc till Lion...)

Looks like on MinGW putenv has to be used instead of setenv/unsetenv, dmalcolm
can you please have a look? I know MinGW is a Tier-NotSupported platform but it
was at least compiling before this change.

Dear Rainer,

I am not so sure that it is a kernel bug but,  rather, it could be a
gcc bug that is affected by differences in the kernel. It seems to me
that this has crept in since the gfortran error.c was completely
reworked to use the gcc error reporting mechanisms. There is now a
flag, which determines whether or not the line where the error occurs
is displayed or not. I suspect that something is causing this flag to
be set or reset. I might not have time today but will certainly test
this in the next day or two.

Regards

Paul

Yes, the mingw build is still broken.

Git has compatibility functions for setenv() and unsetenv():

https://github.com/git/git/blob/master/compat/setenv.c
https://github.com/git/git/blob/master/compat/unsetenv.c

Maybe something like this can be used in GCC as well.

The patch declares the functions but those functions do not exist on mingw-w64,
seems to be this will just fail with an undefined symbol error.

The routines are in liberty and the patch assumes that that they are 
built.  If that's not the
case on mingw-w64, then they will have to be provided by some other means.

            Bug ID: 67556
           Summary: Regex \w doesn't support the unicode character
                    <U+200C>
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal

         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mm.masaeli at gmail dot com
