Code in gcc/libstdc++-v3/libsupc++/guard.cc uses a global mutex to protect
multiple threads from ra
Thanks to ktietz, Elieux, mingwandroid (via IRC) and jwakely (via mail),
the integration of mcfgthread and gcc has been accomplished.
This 9000- patch applies to the gcc-5-branch after all other patches from
https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-gcc-git are
applied.

The type __gthread_time_t is referenced in
gcc/libstdc++-v3/include/std/mutex:157
__gthread_time_t __ts = {
static_cast(__s.time_since_epoch().count()),

I have added a thread model and added its corresponding header files. But it
failed the linker.
The file 'gcc/libgcc/config/i386/t-mingw-pthread' which contained two lines:
SHLIB_PTHREAD_CFLAG = -pthread
SHLIB_PTHREAD_LDFLAG = -Wl,-lpthread
I copied the file to 'gcc/libgcc/config/i386/t-ming
A glance over gthr.h reminds me __gthread_time_t. There seem few requirements
documented in gthr.h.
I discussed this with Adrien Nader on mingw-w64's mailing list a few days ago.
Specifically, here are the two questions:
0) Should __gthread_time_t be a struct or a plain integral type?
The 'struct

Thanks for your reply. :>
However I am still having problems building GCC. (Yesterday stage 1 was ok, but
during stage 2 autoconf just failed to find any standard headers. I am still
struggling with it.)
Once I build gcc successfully I will have a look at that configure.ac. Wish me
luck. (btw t
