Yes, dsrgsun has slightly more up to date versions.

GNU C executables are twice as large only for small files (the library is
more complicated, and not as well organized, so it has higher overhead).
For larger files I would expect the GCC to produce smaller code. And yes,
GNU takes longer to compile; Laser is *really* fast. On the other hand,
programs compiled with GNU execute faster, and the GNU optimizer is a *lot*
smarter than Megamax's (GNU knows not only when to put things in registers,
but also how to change multiplications into additions inside of loops,
so that "for (i = 0; i < end; i++) a[i]=foo(i);" produces the same code
as "for (p = a; p < a[end]; ++p) *p++ = foo(p-a);".

One other note: the library as distributed has a serious bug in the compare
routine for floats. That should be fixed soon; a temporary workaround is
to use doubles instead of floats. This may have been causing your problems.
