Hi,

I tried to build the latest melt-branch (not the generated tarball) on a mac.
Here is the few change required to allow the build (note that it builds but as your
cc/cxx detection still fails, the generated melt-runtime.o and *.so files can't be
loaded with gcc build with cxx).

I removed the test of _POSIX_C_SOURCE in melt-runtime.c because this
makes no sense to test the availability of the poll function that way : just use
the function, the compiler will find it out by itself if it is really defined. Moreover,
this kind of test should be in a configure file, not in a source file. On a mac,
_POSIX_C_SOURCE is not defined by default, and defining it lead to errors
while building other parts of GCC.
