The problem we had with -a was that the compiler options that gnatmake
uses to build your code aren't necessarily the same as those used for
the rebuilt library. We saw this with GNAT Project; IIRC the compiler
options for your code come from package Compiler, those for library
code from package Builder. We saw this because of -mlongcall (PPC
option needed for large programs, not so large under VxWorks whith
lots of memory on the SBC!).

We now rebuild the library with the options we need; see
Makefile.adalib in the adalib/ directory. Note that some GNAT releases
(I don't know about the public GCC) don't include everything you need
for Makefile.adalib to work, I can help a bit if you do go this route.
