[gtkada] gtkada 2.2.1 on mac os x

[jim hopper]

i managed to get gtkada 2.2.1 to build correctly on os x as shared 
libs.  i did as little violence as possible to the original 
make/configure scripts, but some things i just didnt know how to do in 
a manner that would not break other ports.  is there anyone who would 
be willing and able to help me get my patch file into decent shape to 
be integrated with the main line gtkada code its not very large?  i 
only modified each of the Makefile.in, Makefile.common.in, configure, 
configure.guess, and configure.sub.

best jim
