[RFA] small cleanup in buildsym.c

[Joel Brobecker <brobecker at adacore dot com>]

Hello,

While doing some code cleanup in our sources, I noticed that
buildsym had some #if 0 and some #if 1. This patch addresses
the ones that look the most obvious to me, the #if 0. I don't
know why this code was #ifdef'ed out instead of simply deleted.
cvs annotate shows that it predates the public CVS. Since it's
been 8 years, I think we can safely remove them. I noticed one
area where we could actually factorize the code, even if actual
function body is the same as the one line we're replacing, the
function has a comment inside that explains why we're doing
so little.

        * buildsym.c (free_pending_blocks): Remove commented-out code.
        (make_blockvector): Likewise. Re-use free_pending_blocks.
        (end_symtab): Remove commented-out code.

Seems pretty straightforward, but I will run it through the testsuite
before committing.
