Don't rush just yet, see below.

Sorry, that was written in a moment of despair.  It's hard to see your
work go down the drain because of some unrelated problem.

Since then, I already found the culprit: it's the use of (foo)
parenthesized expressions in functions (they do work outside of
functions).  So my plan is to replace the offending functions' bodies
with equivalents that don't use (foo), as part of editing all the
configure scripts that the DJGPP build script for GDB already does.

That's not the workaround I found, but I will try that as well.  If it
works, it's an easier edit than what I had in mind.

Sorry, cannot afford reading everything these days.

Thanks.
