Okay.  I raised the issue on gdb-patches-9JcytcrH/[email protected], as you
suggested:
https://sourceware.org/pipermail/gdb-patches/2020-July/170547.html

Meanwhile, using the kludged work-around, as I previously described,
allows me to move on to the next problem:

   CXX    source-cache.o
   ../../src/gdb-9.2/gdb/source-cache.c:37:10: fatal error:
   srchilite/sourcehighlight.h: No such file or directory
      37 | #include <srchilite/sourcehighlight.h>
         |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   compilation terminated.
   make[2]: *** [Makefile:1656: source-cache.o] Error 1

Now, this should not have happened: there is a configuration test for
availability of source-highlight, which should have conditionally marked
this section of code for omission, (because the source-highlight API is
not present in my MinGW tree).  Yet another GDB configuration bug, which
I will also report on gdb-patches ... I can even offer a one-line patch
to correct it.

That said, I note that you, Eli, do build your GDB with source-highlight
support.  How much of a sacrifice would it be, if I omit it?
