For the record, the problem with scons is that if I just rename .ll to .lpp,
scons complains: "Don't know how to build from a source file with suffix
`.lpp'.  Expected a suffix in this list: ['.lm', '.ll', '.yy']."

This is sad, as I tend to think that the third option would be the cleanest,
at least that consistently names all the files .cpp in gsls/, but
unfortunately it seems we don't know how to fix it.

Thanks for taking the time to test these changes.

I've pushed them now, and look forward to fixing whatever kind of obscure
breakage they cause :-)
