Subject: [PATCH] Improve compiler string shown in version()
With some compilers such as Clang and ICC emulating GCC, using a
version string of the form "GCC $version" can be quite misleading.
Also, a great while ago, the version output from gcc --version started
including the string "gcc", so it is redundant to repeat that. In
order to support ancient GCC versions, we now prefix the result with
"GCC " only if the version output does not start with a letter.
