Comment(by konya.vic@…):

 Just successfully compiled and installed i386-elf-gcc.
 port version: 2.0.3

 My workaround:
 1. use port select to change gcc to gcc42 (i686-apple-darwin11-gcc-4.2.1)
 2. fix the following line in Portfile:

 configure.cc    "gcc -no-cpp-precomp -I${prefix}/include"

 It was using cc as the compiler,
 but cc in mac is a symlink to llvm-gcc, so it will not reflect the version
 of gcc.
 (probably affected by xcode4?)
