Re: gcc-Ada (gnat) for Solaris?

[Jim Wise]

Well, the main issue you'll hit is that you will need a running gnat to build 
gnat. 

If you use OpenCSW's gnat (it's available for i386 and sparc, IIRC), you should 
be able to bootstrap your own using the usual gcc bootstrap instructions. 

Without that, you'll need to follow a two-step dance, starting with gnat built 
for another platform:

A.) use gnat on platform $X to build a $X-to-Solaris gnat cross-compiler

B.) use that cross compiler to cross-build gnat for Solaris

And, optionally

C.) use your cross-built gnat to build gnat again, as a check

I've done this, long ago, when (not entirely successfully) porting gnat to a 
new platform, but since others have done the work, you might as well start 
there. 

In the case of OpenCSW, if you don't want to use their tooling, you could 
always download the actual package files and pkgadd them...
