PATCH: gcc-2.8.0 bootstrap failure (i386-sco)

[Robert Lipe]

> I thought this supposedly worked, or I would have tested it earlier.

It did.   It was broken between the last time I tested it and the
official release.   Since I generally override the build with 
CC=/bin/cc /path/to/configure make bootstrap, I've been immune 
from this. :-(   I've been testing by overrideing the CC becuase
I wanted to be sure it would bootstrap with the native comilers.

This problem is also present in EGCS as of this morning.  It's fixed
by the following completely self-evident patch.   Please apply this
to the most immediate release branch of both EGCS and GCC.

What, you don't see the problem?   Edit x-sco5 and remove the 
trailing space that is present on that line.   This way when 
the code does the test if $(CC) = $(OLDCC), it'll pass.

This is about to become an instant FAQ in comp.unix.sco.programmer...
