It does not compile on Linux.  Here is the error message:

irwin@raven> gnatmake ./x19a_temp.adb
gcc-4.3 -c -I./ -I- ./x19a_temp.adb
x19a_temp.adb:2:05: file "type_declaration.ads" not found
gnatmake: "./x19a_temp.adb" compilation error

There is something strange about how case is interpreted by gnatmake on
Linux.  Anyhow, I converted everything (file names and symbols inside the
file) to lower-case type_declaration, and the result compiles.

irwin@raven> gnatmake x19a_temp.adb
gcc-4.3 -c x19a_temp.adb
x19a_temp.adb:10:38: warning: type of argument "mapform19.x" is
unconstrained array
x19a_temp.adb:10:38: warning: foreign caller must pass bounds explicitly
gcc-4.3 -c type_declaration.adb
gnatbind -x x19a_temp.ali
gnatlink x19a_temp.ali

I have attached a compressed tarball with the corrected files for this test
case that compiles on Linux (and hopefully MacOSX as well).

We now have a working simple test case that generates the run-time error (at
least on my 64-bit box with gnat version 4.3.1-2).

irwin@raven> ./x19a_temp

raised STORAGE_ERROR : stack overflow (or erroneous memory access)

Jerry, did the compressed tarball attachment survive your ISP? If so does it
compile and run properly for you?
