[Image-SIG] Problem compiling 1.1.5 under cygwin

[odonian at gmail.com]

With the latest cygwin version, when I try to compile the PIL 1.1.5
source with "python setup.py build" it seems to hang on the first .c
file

python setup.py build
running build
running build_py
running build_ext
building '_imaging' extension
creating build/temp.cygwin-1.5.19-i686-2.4
creating build/temp.cygwin-1.5.19-i686-2.4/libImaging
gcc -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes
-DHAVE_LIBZ -IlibImaging -I/usr/include -I/usr/include/python2.4 -c
_imaging.c -o build/temp.cygwin-1.5.19-i686-2.4/_imaging.o


i.e. the last line above is the last one displayed and nothing
happens.  Task Manager shows several python processes using up all the
CPU; hitting CTRL-C will get me out of the hang.  With the 1.1.6 trunk
checkout, I see pretty much the same error message as above.  Any
suggestions to get this working?  Thanks.
