[MLB] Patch: Check for GNU nm under AIX 4 and 5

[Robert Boehne]

Alexandre alluded to a patch to do this, but since I have already
tested this one I figured I'd post it in case he hadn't finished his
patch.
I have tested this patch with and without GNU nm from binutils 2.10
under AIX 4.3.3, with g++ and also xlC with AIX nm.  In all three cases
the same two test cases fail (but that's another patch...)


ChangeLog entry:

2001-02-15  Robert Boehne  <address@hidden>
        
        * ltconfig.in: Under AIX 4&5 check to see if we're using
        GNU nm, if so, remove -C from the options to $NM.  The -C
        is required to demangle with AIX nm, but -C means don't
        demangle to GNU nm.
