>Environment:
DJGPP, binutils-2.11.2,. Tests are done in DOS session under Win98SE
>Description:
Both gcc-3.0 and gcc-3.0.1 20010802 (prerelease) built for target 
i586-pc-msdosdjgpp generates assemebler output rejected by GAS (binutils-2.11.2)  if -COFF debugging info is requested (-gcoff) compiiling LAPACK tests 

-gcoff is default for DJGPP so -g is the same as -gcoff

This problem doesn't appear with stabs debugging info.
FORTRAN source (from LAPACK) and assembler output are in 
attached archive

command line:
   g77 -v -save-temps -g -O2 -c xerbla.f
