[New-bugs-announce] [issue7714] configure GCC version detection fix for Darwin

[Fabian Groffen]

New submission from Fabian Groffen <grobian at gentoo.org>:

configure.in contains a check for the compiler in use for Darwin like this:

gcc_version=`gcc -v 2>&1 |  grep version | cut -d\  -f3`

This yields in a wrong answer if the output of gcc -v has "version" in another place as well, such as when --enable-version-specific-runtime-libs is enabled.  A better way to retrieve the compiler version is to use GCC's -dumpversion argument, which works with Apple's GCC 3.3, 4.0.1 and 4.2.1 and doesn't need additional grepping/cutting, etc.

The attached patch uses -dumpversion to retrieve the GCC version, which allows a successful configure run.
