Subject: djgpp+f2c


Does anyone have experience combining f2c and djgpp? I have a largish Fortran
application that survives f2c+cc on workstations, but am having trouble 
using it with djgpp. I can f2c it seemingly with no problems; can make the
.o files too; the problems arise at link time.

I'm using a precompiled source for f2c but am  compiling the libraries myself
with djgpp. The f2c readme discusses things  which may require tweaking, but
it would save a lot of work if someone has already been through this.

(The current  problem is an undefined reference to _open in one of the f2c 
library routines. Turns out open gets #defined to _open if MSDOS is defined;
I tried removing -DMSDOS from the CFLAGS but no luck. Is MSDOS  predefined in
djgpp? Is there something about  _open vs. open I should know about?)


thanks,
