The problem occurred with the free "f2c" f77-compatible Fortran-to-C
translater recently released by AT&T.

All tools used below are the GNU versions.

I suspect the bug lies in the loader.

The preprocessed output of wsfe.c as well as the compiler output
wsfe.s are appended to this bug report.

# The symptom is a relocation error when trying to use the library.
$ cc -v spara.o ../f2c/libF77/libF77.a ../f2c/libI77/libI77.a -lm
gcc version 1.36
 /gnu/lib/ld /gnu/lib/crt0.o spara.o ../f2c/libF77/libF77.a ../f2c/libI77/libI77.a -lm /gnu/lib/gnulib -lc
ld: relocation address out of range in ../f2c/libI77/libI77.a(wsfe.o)


# The library was built as follows:
$ cc -O -S -v /tmp/wsfe.c
gcc version 1.36
 /gnu/lib/cpp -v -undef -D__GNUC__ -Dmc68000 -Dmc68k -Dunix -Dunixpc -D__mc68000__ -D__mc68k__ -D__unix__ -D__unixpc__ -D__OPTIMIZE__ -Dmc68010 /tmp/wsfe.c /usr/tmp/cca11426.cpp
GNU CPP version 1.36
 /gnu/lib/cc1 /usr/tmp/cca11426.cpp -quiet -dumpbase /tmp/wsfe.c -O -version -o wsfe.s
GNU C version 1.36 (68k, MIT syntax) compiled by GNU C version 1.36.
default target switches:

# This is the GNU assembler, dated around October 1989, with the -m68010
# flag permanently turned on.  Taken from an official release on prep.
$ as -o wsfe.o wsfe.s

# GNU loader, snarfed out of the binutils on apple-gunkies around
# October 1989.  Not from an official release.

# Interestingly enough, if this step is omitted, the
# relocation bug above does not occur.  The libI77 makefile says
# the purpose of this step is to eliminate unnecessary symbols
# from the library.

$ ld -r -x wsfe.o
$ mv a.out wsfe.o

# GNU 'ar' and 'ranlib', from the same place as the loader.
