Some Ada compilers have built in support for a preprocessor.
Some companies use the C preprocessor itself as a pre-pass
over the source.
However, we have had good experience with making the
unit of variation be the whole source file. Typically
you can define a small number of primitive types and constants
which can isolate out the environment-specificity from all
other source files. Then you only need to select which
version of this one source file you will use to switch from
one environment to another. Our experience is that this approach
is dramatically more maintainable that spreading #ifdef's or
equivalent out all over the code.
