/Users/andreas/QEMU/qemu/fpu/softfloat.h:60: error: conflicting types for ‘uint16’
/System/Library/Frameworks/Security.framework/Headers/cssmconfig.h:73: error: previous declaration of ‘uint16’ was here
make: *** [ui/cocoa.o] Error 1

Apple's FSEvents.h has #include <Block.h>, which wants
/usr/include/Block.h but due to case-insensitive file system and
include path jungle gets QEMU's ./block.h, which in turn includes
softfloat.h indirectly.

Therefore work around the conflict in softfloat.h itself
by renaming specifically uint16 on Darwin to qemu_uint16.
This fixes the build until we have a more general solution.
