Agreed, Ada provides elegant solutions for that.
But Vincent message seems to be about #ifdef, for which Ada has no
equivallent,
and which is very usefull when you interface several languanges, several
compilers
on several architectures.
Then, the ada definitions of the types are universal but the
representation clauses
are enclosed in precompilation options which can be set according to the
architecture (32/64 bits) or the compiler (aonix has a very specific
approach to record implementation (1) ):
#if defined (Linux)
for T use record ...
#elif defined (aonix)
...
The solution we use is to manage (archive) the sources as .common with
the
precompilation statements, preprocess them with
cpp -D<operating system> -D<ada_compiler> [-traditional (2)]
to build the correct ada source.
Any better solution?
(1) AFAIK aonix is the only compiler which swaps fields in a record
(2) gnu cpp does not like unmatching quotes without this flag
