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