configure output from glibc when using gcc49

While it builds fine, configure seems to think gcc '4.9' is not a valid version of gcc.

Attach config.log from build directory please.
Comment 2 Allan McRae 2013-06-06 00:48:15 UTC 
Also post the "gcc -v" output.  Does it say 4.9 rather than 4.9.0?

Your gcc is given a version with only two components (4.9) instead of the usual three (4.9.0).  I have not build gcc from SVN in a month, but last time I did it reported 4.9.0.  I'll check if that has changed.

Do you alter "gcc/BASE-VER" when building gcc?

You are quite correct; the two-component version number is a direct result of my stupidity.
