Well, I tracked back from the GNU/LilyPond build system - it seems to
originate in glibc, but in the GNU/LilyPond build system it has been
extracted out as a separate library.

By building this with --disable-shared I have obtained a library which
links to guile and ice-9/regex is now working inside Denemo.

Thank you very much for your help. I don't know if there is anything
that it would be good to do upstream as a result of this epic little
voyage ...
