Windows build is broken (fresh mingw, cygwin)

[il71]

$subj,

sbcl versions: 1.2.1 - 1.2.4

latest mingw w64 and cygwin 64.

Build error:

pthreads_win32.h:365:19: error: expected identifier or '(' before numeric constant
 static inline int pthread_sigmask(int how, const sigset_t *set, sigset_t *oldset)

mingw's system header pthread_signal.h:

<---
/* Windows has rudimentary signals support. */
#define pthread_sigmask(H, S1, S2) 0
--->

sbcl's src/runtime/pthreads_win32.h:

#ifndef PTHREAD_INTERNALS
static inline int pthread_sigmask(int how, const sigset_t *set, sigset_t *oldset)
{
...
}

Not sure if PTHREAD_INTERNALS should be undefined for windows, but the following
fixes the build:

--- pthreads_win32.h.orig 2014-07-30 12:20:29 +0700
+++ pthreads_win32.h 2014-07-30 01:16:33 +0700

Obviously it is a workaround, not a right fix.

I believe that was fixed in cd4ef0868ce63dc907ca45dfee44b5c87653542c.
