Subject: glibc depends on gcc 3.2+ -> C99

The problem with uninitialized local variables reminds me of something I
wanted to point out for some time.  glibc now depends on gcc 3.2 which
as a side effect has that glibc functions can now be written in C99.
This excludes functions which are also used outside the project but all
others can use the new language features.

Among other nice additions this means variables can now defined anywhere
in a block.  Just as in C++.  This means there is no need to define a
variable until it is really needed and then the variable should be
initialized right away.

This has the potential or avoiding an entire class of bugs.
