Well, I think I understand the stuff in ltconfig, but this seems to
require some supporting code in libtool.m4.  This is the code that I
don't completely understand.  I am not an expert on m4 or configure
scripts (or libtool for that matter) so it is not clear to me what this
is doing, is it compiling conftest.c when libtool is run or when libtool
is being built/installed?  Also, I don't really want to mess with $LD
(ld has no 32 or 64 bit flag anyway and would complain if I tried to
pass it one), is there another way to send the 32/64 bit setting into
ltconfig?  Can I just set my own variable for ltconfig to check?  I
suppose I could use CFLAGS, but I would have to differentiate between HP
C and GCC since they use different flags.
