Building libada on Solaris 10/x86 fails when compiling g-catiio.adb:
$ ../../xgcc -B../../ -c -g -O2 -fPIC -W -Wall -gnatpg g-catiio.adb -o g-catiio.o
xgcc: Internal error: Segmentation Fault (program gnat1)
Running gnat1 under gdb reveals that this happens due to extremely deep
recursion in
Program received signal SIGSEGV, Segmentation fault.

This went on to a depth of 76000+ when I aborted gnat1. The problem exists
with the default stack size of 8430 kB; if I increase the stack size limit
to the max (i.e. 130336 kB), the compilation succeeds. While this might be
a workaround, I don't consider it a solution.
