As far as I know, there is no way to build a MSDOS compiler
from current FSF sources. I'm not aware that MSDOS support
ever has been complete in the sense that it would be able
to produce results from the Ada test suites.
While I'm sympathetic to maintaining support for old systems,
having kept OS/2 support going until well past the expiration
date of that system, if you look at what this patch removes
it is mostly obsolete comments and documentation. The actual
OS/2 run time support, which implemented the entire language
including all optional annexes and passed validation, has
been gone for a long time. For MS-DOS there never has been
such full support.
Note that if you have an environment where you can build current
FSF sources on DOS, this should still result in a valid Ada
compiler. This patch mostly removes comments as you see and
should not affect your ability to build the compiler.
If this patch breaks bootstrap of the Ada compiler on your
system, feel free to submit a patch for re-instating those
parts that are still needed.
