DOS ain't dead

On May 18, Andris Pavenis announced GCC 10.1.0 for DJGPP 2.05:

Further testing is, of course, welcome.

One regression seems to be that temporary file names need LFN support.
Perhaps it will be refreshed and fixed soon (reported by me to newsgroup).

A useful change is "-finline-functions" is now default, even for -Os or -O2.
This should help more than it hurts, IMHO.

How it behaves on non-LFN system? Doesn't compile neither simple file?
I just quickly tested it few days ago but under WXP so I had LFN and didn't notice the problem.

DOS gives me freedom to unlimited HW access.

This extremely annoying, unnecessary problem also plagues the AdvanceCOMP DOS ports as well:

These utilities are indespensible. Recompiling from souce after having eliminated the LFN Temporary files requirement seems like a nightmare, especially since no make file is provided. The source indicates that .tmp files are appended with the Unix elapsed time since the epoch began, and this makes all such temporary files created > 8.3 chars. Needless, and stupid!

Andris says: "It seems that I have forgot to cherry-pick one change from port of gcc-9", referring to this diff for collect2.

Andris did announce GCC 10.2.0 over a month ago (24 July), and indeed it fixes the SFN regression. Grab it from a local mirror, e.g. /current/v2gnu/.
