JMarc has already run into this one. It's been reported to Karl (sigc++
maintainer) but it looks like cxx reads every line of the file even the
ones it knows it doesn't have to interpret -- looking for preprocessor
directives it doesn't understand so it can give you a warning.

Do either of you (Angus and JMarc) have SGI's STL installed or are
prepared to install it? I'm wondering if it's a compiler problem or a
problem with the way Compaq/Digital have written their library. Try
compiling both with and without-included-string with SGI's STL.

I would have thought that gcc should have included these headers or
something like them in its distribution.

xtl really needs an xtl_config.h

That's an interesting warning. I should have a look at the code there and
see what it isn't doing as a result.

I better do some more reading in xtl's code.
