Version 1.3.5, built with

  ./configure ... --includedir=/usr/include/fltk

Why do we (Gentoo) do that? I can only guess. Since we're a source-
based distribution, installing a package means building it, and that
requires us to install the development headers for everything. As a
result we tend to be the ones who find out that two headers from
different packages share the same name. My guess is that some FLTK
header has the same name as a header from another package. By putting
the headers in subdirectory, we avoid the name clash.

No problem, I'll drop that commit.
