/* Implementations of SwigCgocall and friends for different versions
of gccgo. The Go code will call these functions using C names with
a prefix of the module name. The implementations here call the
routine in libgo. The routines to call vary depending on the gccgo
version. We assume that the version of gcc used to compile this
file is the same as the version of gccgo. */
