Forum: Ruby-core unable to build trunk [doze]

In Mingw, I get the following with trunk

gcc -O3 -g -Wall -Wno-unused-parameter -Wno-parentheses
-Wpointer-arith -Wwrite-strings -Wno-long-long -I.
-I.ext/include/i386-mingw32 -I./include -I. -DRUBY_EXPORT   -o win32.o
-c ./win32/win32.c
./win32/win32.c:5277: error: syntax error before "sizeof"
make: *** [win32.o] Error 1


Following seems to help it.

though I'm not sure if that's the best way or not.  Appears mingw
already defines signbit for us?

I can confirm when attempting to build both 26818 and 26819 with 
Msys/Mingw using gcc 4.4.0:

gcc -O0 -pipe -g3 -ggdb -Wextra -Wno-unused-parameter -Wno-parentheses 
-Wpointer-arith -Wwrite
-strings -Wno-missing-field-initializers -Wno-long-long -I.

I've forgotten to commit the fix.  Thank you.
