Just tried compiling ruby TRUNK with mingw 4.4

The result this time?

In file included from ../ruby_1_9/signal.c:531:
c:\dev\ruby\rubyinstaller\sandbox\mingw\bin\../lib/gcc/mingw32/4.4.0/../../../../include/pthread.h:307:
error: redefinition of 'struct timespec'
make: *** [signal.o] Error 1
rake aborted!
Command failed with status (2): ["C:/dev/ruby/rubyinstaller/sandbox/msys/bi...]

Anybody else run into this before?  Is this perhaps the existence of
pthread on a windows platform throwing it for loops?
