Yeah, lucky they don't need to reinvent the wheel every time the 
GCC/libgcc interface changes. :-)

If GCC generates a call to a libgcc function that calls a libc function, 
I'd consider that a pretty serious bug, given that said libc function is 
likely to consist of GCC-generated code, which could call the same 
libgcc function, which calls the libc function, etc.

I'd say problems are more likely if you use nonstandard implementations 
of GCC internals...
