Re: GCC viciously beaten by ICC in trig test!

This is a tricky issue. Some standards (e.g. POSIX) make conflicting

standards too -- in order to comply with user expectations.
That is a mess and GCC has better not drive into that.

Perhaps GCC could provide a clean ISO C library that is enabled with the -std=c99 switch? After all, GCC does include an ISO C++ library, and a Fortran 95 library (in tree-ssa).

The compiler could link against the system C library, except when the user explicitly declares that they wish to use the GCC-supplied library.

I've also noticed a couple of alternative libraries for embedded systems (uClib and newlib). I may experiment with these...
