OpenJDK 1.7 OS/X 32bits

[Henri Gomez]

64bits VM build works on 64 bits machine/kernel OS/X :

I tried to build 32bits VM, still on 64 bits machine/kernel OS/X,
using the following patch
(http://code.google.com/p/openjdk-osx-build/source/browse/trunk/patches/Platform.gmk.patch)
If ARCH_DATA_MODEL=32, ARCH=i586 (even on a 64bits machine) but it failed with

Looking around line 27 of hotspot/src/os_cpu/bsd_x86/vm/bsd_x86_32.s :

#ifdef __APPLE__
# Darwin uses _ prefixed global symbols
#define SYMBOL(s) _ ## s
#define ELF_TYPE(name, description)
#else
#define SYMBOL(s) s
#define ELF_TYPE(name, description) .type name,description
#endif


Any ideas ?
