-fbacktrace

[Philippe Schaffnit]

Hi!

Thanks a lot for your reply!

I was wondering about this cc1 too, but I thought it somehow came from
the error handling:

The (lengthy) command:
gfortran -m32 -O1 -g -fbacktrace -pedantic-errors -Wall -x f95-cpp-input
-std=gnu -ffpe-trap=invalid,zero,overflow,denormal -fbounds-check
-Wextra -Wunused -Wunderflow -Wsurprising -Wline-truncation -Waliasing
-DEIN=1 -DAUS=0 -DSGI=1 -DINTEL=2 -DLAHEY=3 -DSUN=4 -DGCC=5
-DKOMPILATOR=5 -DTC_KOPPLUNG=1 -DFLEXLM=0 -DZLIB=1 -DIRIX=1 -DWINDOWS=2
-DLINUX=3 -DSOLARIS=4 -DBETRIEBSSYSTEM=3 -DNO_METACHARACTER=0
-DDEFAULT_DOUBLE_PRECISION=0 -DDAY=15 -DMONTH=05 -DYEAR=2007
-DCHECKMODUS=1 -c
/USER/Alpha/Sim/SimF/philippe/MICRESS/MICRESS_KornStrebe/MICRESS/main/main.f90

The error message
cc1: error: unrecognized command line option "-fbacktrace"

gfortran -v

What really surprises me, is that it was still working with Friday's
sources, and I don't think I have changed anything to my makefile
since...

Cheers!
