/**
* Declare a function with libgcc implicit linkage
*
* It seems as though gcc expects its implicit arithmetic functions to
* be cdecl, even if -mrtd is specified. This is somewhat
* inconsistent; for example, if -mregparm=3 is used then the implicit
* functions do become regparm(3).
*
* The implicit calls to memcpy() and memset() which gcc can generate
* do not seem to have this inconsistency; -mregparm and -mrtd affect
* them in the same way as any other function.
