Hello,
this patch adds some errno values supported by newer runtime-version.
To keep backward compatibility
this patch checks for their definition before trying to use them.
Especially the EPERM error-number is required for having ISO-C++0x
std::thread support enabled with
winpthread libary for 32-bit and 64-bit Windows host.
ChangeLog
2011-08-28 Kai Tietz <kti...@redhat.com>
* config/os/mingw32/error_constants.h (ECHILD): Add support,
if present.
(ENOSPC): Likewise.
(EPERM): Likewise.
Bootstrapped and regression tested for x86_64-w64-mingw32 and
i686-w64-mingw32. Ok for apply?
Regards,
Kai
