[ada] help debugging acats failure

[Geert Bosch]

If you pass -v to gnatmake, it will output the gcc invocations.
This should be sufficient to find the problem.

Basically, just go to the directory containing c35502i.adb, and
execute the gnatmake command as listed below, with -v added in.
If you only have the 35502i.ada file available, use "gnatchop  
35502i.ada"
to get the various units split out in their own files.
You might need to specifically include the "support" directory,
which appears to be /home/rth/work/gcc/bld-sjlj/gcc/testsuite/ada/acats0
from your report.

Hope this helps.
