Re: LD scripts - using expressions correctly

OK - I have no idea why I can't get it to build (HAVE_LIMITS_H is
definitely defined via the configure step) but that's a problem for
another thread.

Re the expressions problem, I tried using Alan's re-written version
and it works perfectly when using the current version (2.24) of
Binutils.  A bit of experimenting seems to show that it's the "+="
operator that's up to mischief so I've removed all uses of it from my
scripts, and they're working fine now.

Thanks to Alan for his help, and remember folks, when using LD, just
say "No!" to += :-)
