question: gnulib modules that only exist in coreutils?

[Assaf Gordon]

Hello,

I'm trying to use "gnulib" in my project.
I would like to use some modules that seem to exist in the 'coreutils' version 
of 'gnulib', but not otherwise.

specifically: strnumcmp and randread (but later perhaps others).

In coreutils, the files do exist:
===
$ cd coreutils
$ find -name "*randread*"
./gl/lib/randread.c
./gl/lib/randread.h
./gl/modules/randread
./gl/modules/randread-tests
./lib/randread.c
./lib/randread.o
./lib/.deps/randread.Po
./lib/randread.h
===

But gnulib-tool doesn't recognize these files (compared to other modules, which 
it does:
===
$ ./gnulib/gnulib-tool --find lib/xstrtold.c
xstrtold
$ ./gnulib/gnulib-tool --find lib/randread.c
gnulib-tool: warning: file lib/randread.c does not exist
===

And so I can't add them with "--add-import" in my projects.

Any advice is appreciated.
