Hi Rich,

That just means you'll have to install gettext there.
That will provide things like the libintl library and
the missing header files.

Note that some projects used to include an intl/
directory, and that gave them libintl.a as well as libintl.h
as a result of the usual ./configure && make process: i.e.,
no need for an external library.

However, these days, it seems that most projects prefer not to
include all of gettext's intl/ directory.

stpcpy is another useful one (though currently not used in libvirt).
Lets you do successive string concatenation cleanly and
without the usual O(N^2) penalty that you get when doing
it via strcat.

This is such a thin wrapper that it should be easy to
justify changing to LGPLv2.
