Those are fairly common, particularly the latter.

The correct solution is to use:
That's why those switches exist.
[Actually, the "real" solution is for the authors of substantial
middleware packages such as Tcl/Tk and PostgreSQL to use a prefix
directory for headers, as is the case for OpenGL and X11.]

configure does not attempt to guess which directories you want the
compiler/linker to look in; you have to tell it. If you don't use any
--with-*-includes or --with-*-libs switches, the only directories
which will be used are those in the compiler's/linker's default search
This is intentional, and won't change. It used to do path-guessing;
that was removed for a reason, and that reason is still valid.
[Specifically: on some systems, it would break the build, and no
combination of switches would fix it. When it does the right thing,
path-guessing provides a minor convenience (i.e. it saves you from
typing a couple of switches). When it does the wrong thing, you simply
cannot build GRASS.]
The only exception is for X, where the configure test attempts to
determine the appropriate switches via Imake, but allows them to be
(partially) overridden via the --x-includes= and --x-libraries=
switches. This behaviour is built into autoconf.
