[PATCH] Check for valid value of BASEVER

["Daniel Richard G." <skunk@iSKUNK.ORG>]

[-- Attachment #1: Type: text/plain, Size: 793 bytes --]

In the event of a missing or mis-read $(top_srcdir)/gcc/BASE-VER file, this 
patch (against 4.2.3) will cause gcc/Makefile to throw an immediate error, 
instead of allowing the bootstrap process to continue on to an eventual ICE 
(due to an empty version string, in regular GCC releases).

See the Bugzilla entry for some more background on this:
