Does your README-hacking file say that building with
--enable-gcc-warnings is only supported on glibc systems with
recent enough GCC? It is known that on other platforms and with
older GCC versions, gcc shows ma

I was thinking of an additional option that would automatically decrease
-n so that the requested number of processes is started (then of course
the load may not be well balanced).
So you mean, rather than the current situation of:
$ yes . | head -n13 | xargs -n4 -P2
. . . .
. . . .
. . . .
.

Shouldn't this use gl_MANYWARN_C
With these two change sets, ./configure --enable-gcc-warnings && make
in builds with most warnings enabled also in lib/.
To make that work, I've chosen to disable-in-lib/ some warning options, via
-Wno-missing-prototypes
-Wno-uninitialized
-Wno-unused-macros
-Wno-old-style-definition"

Grr. An argument for_not_ splitting.
It is indeed that way.

Some programs, like 'msgmerge' from GNU gettext, already pay
attention to the OMP_NUM_THREADS variable - a convention shared
by all programs that rely on OpenMP. Can you make the 'sort'
program use the same convention?
I am not working on the multi-threaded sort, but if somebody asks I can
