Comment 1:

The way to do this would be to parse the output of gcc -dM,
as the various scripts in src/pkg/syscall do.

Labels changed: added cgo.

Comment 2:

I have a patch to do this, but it's somewhat fragile for simplicity's sake. For
instance, if you use a #defined constant, say C.FOO, and FOO looks like
#define FOO some_func_call()
or something similar, it will translate into invalid Go code. I personally think this
is OK, because it doesn't make much sense to use defines in this way with the cgo
FFI. Additionally, it's quite a pain to try to parse C further to determine whether
it will, in fact, generate valid code.
Other than that, seems to work. Patch attached so I don't lose code; contains fixes
for two other cgo issues though, just waiting for Russ to get back so we can get
things committed cleanly.
