Well, I think I already knew this, but the g95 Makefile already has
the correct CFLAGS in it:

(from /usr/pkgsrc/lang/g95/work/g95-0.92/Makefile)

CFLAGS = -O2 -march=mips3 -mabi=32 -DIN_GCC -Wall -Wmissing-prototypes

But the failure is with this other software inside the g95 source dir:

gcc -DHAVE_CONFIG_H -I.     -D_FILE_OFFSET_BITS=64 -DHAVE_REAL_10=0 -fPIC -g -O2
 -MT mutex.o -MD -MP -MF .deps/mutex.Tpo -c -o mutex.o `test -f 'runtime/mutex.c
' || echo './'`runtime/mutex.c

When I do "make configure" for g95, it apparently does not build a
Makefile for libf95:

root <at> taz:/usr/pkgsrc/lang/g95 # cd work/g95-0.92/libf95.a-0.92

I don't know enough about hacking pkgsrc to make this happen properly,
or to make the CFLAGS get put into the makefile for this libf95
software.

I'm going to try setting a CFLAGS variable with the CFLAGS line from
the g95 Makefile to see what happens. The problem is, it takes me a
few hours to know if it failed :)
