 GCC 3.4 or newer, GCC 4.1 recommended
 
-The GNU C library can only be compiled with the GNU C compiler family.
-For the 2.3 releases, GCC 3.2 or higher is required; GCC 3.4 is the
-compiler we advise to use for 2.3 versions.
-For the 2.4 release, GCC 3.4 or higher is required; as of this

 On certain machines including @code{powerpc64}, compilers prior to GCC
 4.0 have bugs that prevent them compiling the C library code in the
 2.4 release.  On other machines, GCC 4.1 is required to build the C
 library with support for the correct @code{long double} type format;
-these include @code{powerpc} (32 bit), @code{s390} and @code{s390x}.

 You can use whatever compiler you like to compile programs that use GNU
 libc, but be aware that both GCC 2.7 and 2.8 have bugs in their
