The only thing which worries me about this is that it increases the
likelihood of overflowing limits on the command line length (which may
be unreasonably low, especially on W95/WNT and IRIX 5).
We've already had to change modules.m once to avoid overflowing
fixing limits (in the rule for creating libfoo.split.a on IRIX 5 --
see the CVS log message).

So if you want to make this change, then I think it is important to
test it on W95 and IRIX 5.
