Hmm. I have the native compiler and the cross compiler installed in the
same place, and while gprbuild is perfectly happy with this and the
internal 'for Target use "arm-eabi";' GPS isn't; nor does it pass the
Default_Switches ("ada") "--RTS=" to the compiler.

GPS seems to be far too complicated a tool to use without support.

I can get the AdaCore demo to build with my RTS, with a little
difficulty (interrupt names changed, I didn't realise a main program can
have a priority) but it doesn't run; possibly some problem with clock
configuration, anyway it looks as though it's stuck in an interrupt.

I was looking at GPS so that I could see how you can navigate from
something's use to its declaration. I *think* you

* click on the object of interest (in this case, EXTI0_IRQ)
* menu Navigate > Goto Declaration

I know that the Linux version of the cross compiler has the RTS files in
some bizarre location; if you've installed in C:\GNAT2014 they _should_
be in C:\GNAT2014\lib\gcc\arm-eabi\4.7.4\rts-ravenscar-sfp-stm32f4.

I kept a copy in my RTS project, see
