Compiling on macosx

[Benjamin Dasnois]

Hello,
I've got a little problem when trying to install gnustep on macosx.
While trying to compile the gui module I've got this error:

In file included from ../Headers/AppKit/NSGraphicsContext.h:109,
                from Functions.m:35:
../Headers/Additions/GNUstepGUI/GSMethodTable.h:111: error: parse
error before 'size_t'
