I don't find it (libgcc.a). the closest I find is gcc.lib on 
my gcc 2.6.3 setup at work.  I am not at home right now, 
so I can't check.

Well, I have indeed had success with gcc 2.6.3, but not with 2.7.2 anymore.
Being completely stupid I didn't just upgrade emx rts from 09a to 09b but
did the wole works (2.6.3 -> 2.7.2) assuming that's a VERY GOOD THING.
Maybe it wasn't. I'll restore my 2.6.3 and just put in the nwe emxrts
tonight. Or, maybe I live with the separate link step until a 2.7.2 version
is out?

Is this how g77 does it with f2c.lib?

Oh -- by the way: What's the reasone for gpc/emx being >= 3 MB as opposed to
1.7 or so it was before? Is it the turbo stuff, or is it debug info that one
could safely strip out?  Cheers!  Stefan (also Dipl. Phys.)

PS: A last one: I see mail to gpc at hut.fi bouncing all the time. You too?
