Information on f2c-stabs package

f2c does name mangling, auto array referencing, pointer passing, and
parameter realization when compiling Fortran code to C code.  This
makes debugging f2c code from within gdb very difficult.  This
package, when used in conjunction with running gdb from within emacs,
solves alot of this problem.  It allows emacs to take fortran
expressions, convert them to the f2c mangled version, and pass them to
gdb for evaluation.  For example, if one has:

REAL FOO(2:3,1:2)
COMMON /BAR_NONE/ FOO

one can do C-cC-v foo(3,2) in emacs to get the value of FOO(3,2).
Emacs will automatically translate this to bar_none__.foo[4], and pass
it to gdb for evaluation.

The package include the above emacs elisp code, a fortran parser, and
other miscellaneous utilities.
