Hi folks,
There is a problem with compiling C++ code using mathinline.h. The
inline function signatures do not match the prototypes in
mathcalls.h. The prototypes in mathcalls.h include a throw specifier
(AFAICT from __MATHCALL), but the functions in mathinline.h lack this,
leading to build failures:

This has been filed as Bug #340871.
I'm not familiar with glibc/m68k, but adding __THROW to the inline
functions should be all that is required.

Roger
