-/* This program is a wrapper to the main `gcc' driver. The generic
- goal of this program is to be basically identical to gcc (in that
- it faithfully passes all of the original arguments to gcc) but,
- unless explicitly overridden by the user in certain ways, ensure
- that the needs of the language supported by this wrapper are met.
-
- For GNU Fortran (g77), we do the following to the argument list
- before passing it to `gcc':
-
- 1. Put `-xf77', `-xf77-cpp-input' or `-xratfor' before each list
- of foo.f, foo.F or foo.r source files and put `-xnone' after
- that list, if necessary. This shouldn't normally be necessary,
- but it is done in case gcc.c normally treats .f/.F files as,
- say, to be compiled by f2c.
-
- 2. Make sure `-lf2c -lm' is at the end of the list.
-
- 3. Make sure each time `-lf2c' or `-lm' is seen, it forms
- part of the series `-lf2c -lm'.
-
- #1 is not done if `-xfoo' is in effect (where foo is not "none").
- #2 and #3 are not done if `-nostdlib' or any option that disables
- the linking phase is present, or if `-xfoo' is in effect. Note that
- -v by itself disables linking.
-
- This program was originally made out of gcc/cp/g++.c, but the
- way it builds the new argument list was rewritten so it is much
- easier to maintain, improve the way it decides to add or not add
- extra arguments, etc. And several improvements were made in the
- handling of arguments, primarily to make it more consistent with
- `gcc' itself. */
