Proposed PATCH: -classpath and -CLASSPATH options

[Tom Tromey]

Some background: for Java, we'd like `gcc -femit-class-files' to be
compatible with Sun's `javac'.  As a result we'd like a `-classpath'
option to gcc that takes an argument (the class path).

We also want a -CLASSPATH option that has a similar, but slightly
different, meaning.

There doesn't appear to be any way to specify a language-dependent
option which takes a separate argument.  Furthermore, a comment in
gcc.c leads me to believe that this is considered impossible.

Therefore I wrote the appended patch, which adds `classpath' and
`CLASSPATH' to DEFAULT_WORD_SWITCH_TAKES_ARG.

Here is a ChangeLog entry:

Fri Oct 16 12:26:09 1998  Tom Tromey  <tromey@cygnus.com>

	* gcc.c (DEFAULT_WORD_SWITCH_TAKES_ARG): Add classpath and
	CLASSPATH.
