At least in 4.4, 4.5, and 4.6, as I see, libgcc functions are assumed
to be cdecl even with -mrtd.

I don't know any GCC switch which disables calls to libgcc functions.
These are used, for example, to implement long long integer division
(happens in classpnp, and it's compiled with -mrtd).

-fno-builtin, it disables built-in functions such as cos or strlen.

But now with -mrtd, the suffix is not added even to functions
explicitly declared as stdcall.
