Bugzilla fortran tech support:

  I have attached a compressed archive that should allow you to reproduce an
Internal Compiler Error. Place the file in a directory, decompress it, and
extract its entire contents. Then enter

automake
autoconf
./configure
make

  When I do this I see the following compiling the file syspars.f90:

gfortran  -I/home/norm/opcon/gfortran/focus11-bug1-4.7.1-test-dir/include -c -v
-Wall -Wextra -O3 -ffast-math -funroll-loops -std=f2003 -fno-backslash -c -o
syspars.o  syspars.f90
Using built-in specs.
