OK, my words were incorrect. The compiler is OK, but the libc is
buggy. But: A compiler without library is nonsens, at least for
all non-system (non-kernel) development. E.g. the JAVA distributions
must contain a huge set of libraries, otherwise no one would call them
as "compiler+runtime".

I'm not so familiar with the Linux world, I'm very familiar with
JAVA and commercial C compilers like the Watcom. Therefore, in my 
opinion the libraries are part of the compiler distribution (as it is 
e.g. for the Watcom C compiler).
