>Description:

Xlint appears to have a bug.  It issues many of these:

	warning: integral constant too large

when in fact there is no such problem.

>How-To-Repeat:

Run xlint (lint) on virtually any C source file.

>Fix:
	
It turns out that this is really a bug in gcc 2.7.2.1.
Gcc -O fails to compile toicon() in lint1/cgram.c correctly.
To work around this:

1. Build xlint normally.

2. Delete lint1/cgram.o.

3. In the top-level xlint directory say

	make CFLAGS=

   (define CFLAGS to be empty).

   This will recompile just lint1/cgram.c without
   optimization, giving you a new lint1/lint1.

   NOTE: You MUST do this from the top-level xlint
   directory, not from the lint1 subdirectory.

4. Install the new lint1 in /usr/libexec.
