Patch for fixinc `sun_catmacro'

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

	I found another problematic diff with SunOS4's egcs-1.1.2
fixincludes vs. that from "gcc-2.96 19990606".  I traced it to a
failure in the Sun_Catmacro fix.  (The snippet below is small enough
that it should be okay to post.) :-)

	The problem is the "select" pattern never matches the line in
the header because the parens aren't escaped, thus the fix is never
run.  The patch below fixes it.

Note I used mixed quote styles because I needed to have double quotes
to have \t expanded to a real TAB, but the backslash parens needed
single quotes to do the right thing.

I am not experienced in autogen to know if this was sensible though.
Maybe one could use double quotes around the whole thing and use \\(
instead of \( ?  I didn't test that form though.  Bruce?

	Which ever fix is used, its needed for both trunk and branch.

	* inclhack.def (sun_catmacro): Escape the parens and use single
	quotes around them, but keep double quotes around the \t.
