This relates to building TASH as a library (static, libtash.a) using
GNAT Project, as in GNAT-GPL-2007.

As well as Ada source, this library needs two C-sourced units to act
as wrappers for macros in the Tcl/Tk header files.

I can do this by hand (obviously only for a static library) by doing
this after gnatmake has done its part:

   gcc -c -g -O2 -I/usr/include tclmacro.c
   gcc -c -g -O2 -I/usr/include tkmacro.c
   ar -r lib/libtash.a tclmacro.o tkmacro.o
   ranlib lib/libtash.a

but can't help feeling there should be a way to tell gnatmake to do
this!

So far I have

with "../tash_options";
