It's been a few years since I tried gm2. I didn't write any heavy code
in it, just played around a bit.

Normally "SYSTEM" is a pseudo module only used for non-portable code,
but I don't know how gm2 is supporting it here.

In recent years I did dabble in Modula-2 but only for simple homegrown
text utilities, nothing brilliant.

(I also keep playing around with Pascal and Oberon in FreeDOS, all of
which I've been toying with for a few years. Lately it's mostly been
Pascal although I also ported some very trivial stuff to C and
FreeBASIC.)

I did buy a StarLabs Linux laptop (Ubuntu LTS) last year but haven't
used it much. I never installed GCC (or any compiler) on it. GCC 13 is
really new anyways (but yes, Modula-2 directly interests me). Cygwin
is still apparently using GCC 11.

I know I tried a few times with G++ 7 and 9. Since p7zip is older code
(and last updated in 2016), it does need "-std=gnu++98" or such
because the default is now C++17. So it always had some bugs and
limits but "mostly" worked.

I normally avoid LFNs in DOS, but rarely I'll load up DOSLFN (TSR). I
doubt FreeDOS 1.3 changed much. It might even have regressions. I'm
still using the older 2041 kernel (latest is 2043) locally on my old
2010 Dell laptop (booted via USB stick). Honestly, I long ago
downloaded FreeDOS 1.3 but haven't installed it under VM yet. I'm
pretty sure it's all fairly minor changes.

Specifically I meant if LFNs are required. I know it can (or used to)
work in various OSes. I just was not 100% sure whether which ones were
directly supported. Locally I never use LFNs if I can help it. It's
just not necessary (for me).

Well, Modula-2 already had them 40 years ago, lol. But it's a huge
change. (Bjarne says it's 10x faster, but I suspect it will take
forever for everyone to catch up and migrate. He did publish a new
_Tour_ book last year, which I haven't bought yet, but it sounds
interesting.) FYI, gm2 supports both Wirth's PIM Modula-2 and the 1996
ISO 10514 standard (with complex numbers, C++-compatible exceptions).
Although I really like Pascal (in various forms, e.g. GPC Extended
Pascal has modules and --automake), Modula-2 was Wirth's "successor"
language (but before Oberon). They're all good in different ways. I
actually cobbled together a DJGPP build of M2C years ago. It has some
glaring bugs but still somewhat works.

Just FYI.
