* configure.in (CC): Restrict allowed GCC versions to 4.3 and
later. Allow versions 5-9.
* configure: Regenerated.
* manual/install.texi (Tools for Compilation): Give GCC 4.3 as
required minimum version and 4.6 as recommended version. Do not
mention bugs in GCC 2.7 and 2.8.
* INSTALL: Regenerated.

GCC 3.4 or higher is required; as of this writing, GCC 4.4 is the
compiler we advise to use for current versions. On certain
machines including `powerpc64', compilers prior to GCC 4.0 have
bugs that prevent them compiling the C library code. On other
machines, GCC 4.1 is required to build the C library with support
for the correct `long double' type format; these include `powerpc'
(32 bit), `s390' and `s390x'. For other architectures special
compiler-provided headers are needed (like `cpuid.h' on x86) which
only come with later compiler versions.
GCC 4.3 or higher is required; as of this writing, GCC 4.6 is the
compiler we advise to use to build the GNU C library.
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 floating-point support that may be triggered by the math
library.
