mask __SIGRTMIN{,+1} on glibc linux only
Hello,
src/libgcc/generic-morestack.c currently (as of 4.6.2 in
debian, which was updated to r184373 for the 4.6 branch) in
__generic_morestack_set_initial_sp() masks out __SIGRTMIN and
__SIGRTMIN+1 on all glibc platforms (ifdef __GLIBC__). It used to do
that on all linux platforms (ifdef __linux__). I guess the change was
made to avoid issues with uclibc and such on linux, but on the other it
brings issues with glibc on other ports that linux: NPTL is only ported
to Linux, and I doubt there'll be other ports actually, since it is so
much tied to the Linux kernel.
It should thus turned into if defined(__GLIBC__) && defined(__linux__),
as attached patch does.
