Is the above change really necessary? Would be nice to get rid of this

It is required for support of environment when LFN support is either
not available or disabled for some reason (for example FreeDOS
without LFN support loaded).
Does it matter for GNAT usage/users in practice?

It may. I do not actually have information about environments used by poeple using DJGPP build. I'm
providing compiler packages for them.
There are actually 2 levels of non-LFN support for DJGPP port of CCC:
1) ability to run user compiled programs (the ones which are compatible with required restrictions)
without LFN support
2) the ability to compile using GCC in such environment
Submitted patches only addresses level 1. I'm not sure I'll ever submit changes for level 2.
Absence of these changes does not prevent bootstrapping GCC iwhen LFN is available (like in recent
Windows versions).
Discussed change belongs to level 1 (ability to run compiled programs without LFN support available).
