Would it be possible instead to make it a --configure option, or just
to add a note to the Solaris FAQ about adding an option to CFLAGS?
I'd be leery of automatically replacing system libraries, if only
because it might surprise people. Clearly the improvement is a win
in this case, but if Sun fixes their library, it might be yet faster.
(By the way, I've been following this thread, and noticed that the
problem shows up with gcc 2.95; AFAIK, 2.95 couldn't generate 64 bit
Solaris binaries, so we can be fairly certain the problem is in the
32 bit library. Maybe the 64 bit one is better? I _may_ have time
to check this week, but it's looking unlikely. If no-one else does,
I'll try it out as soon as I can.)
