because go32 compiled with BC 3.1 did not have problems with the times
reported by stat(), whereas go32 compiled with TC 2.0 gives bad values
for st_[mca]time.

I was blissfully unaware of the potential for legal problems here.

Actually, I don't care which compiler is used to build go32, as long
as the executable that is produced _works_ . The current solution does
*not* work properly when you set the TZ variable as needed by the
routines in libsrc/c/gen/ctime.c (TZ=MET-1METDST-2,M3.5.0/02:00,M9.5.0/02:00
in my case): stat() and ftime() breaks. For stat(), this is due
to the _TC_ stat() breaking on this TZ setting; I haven't checked 
ftime() yet - only the gmtoffset and dst flag breaks - but presuma-
bly it is for the same reason.

There are a couple of ways to fix this, that I can think of:

1) All is well when go32 is compiled with BC 3.1. This was the simplest
solution - no changes required in go32 or GNUO sources. Only legal problems.

2) Rewrite the go32 implementation of stat() and ftime(), so they don't
rely on the broken TC library routines. Could be done, but a bit more
work.

3) (This is probably really part of 2): Get the TZ routines in ctime.c
working, so a TZ setting of 'MET-1MDT' is handled properly, instead of
bailing out and ignoring the DST setting.
