I was under the impression that kpathsea allows one to search for files
in all subdirectories of some root directory, but I suppose that is true
only for octave itself, not gcc.

I'm using ncurses-devel-1.9.9e-4.i386.rpm which is the one shipped with
Red Hat 4.2, and it puts the files into directories as follows:
/usr/include/curses.h
/usr/include/eti.h
/usr/include/form.h
/usr/include/menu.h
/usr/include/ncurses.h
/usr/include/ncurses/curses.h
/usr/include/ncurses/eti.h
/usr/include/ncurses/form.h
/usr/include/ncurses/menu.h
/usr/include/ncurses/panel.h
/usr/include/ncurses/term.h
/usr/include/ncurses/termcap.h
/usr/include/ncurses/unctrl.h
/usr/include/panel.h
/usr/include/term.h
/usr/include/unctrl.h
I don't know the rationale behind this.

Well, I've overkilled now by (a) running autoconf and autoheader
(b) adding an empty src/libieee.a (c) editing specs
(d) rerunning ./configure
The 'make' is now churning in the background and I still see -mieee-fp
among the compiler options, but hopefully overkill item (b) will
fix that.
