Subject: gawk ported to MINIX-386, c-news port in progress, & bug reports

I've been working on porting C-news to MINIX, and as part of the process
I've found that bawk couldn't handle the c-news awk scripts.  So, I
grabbed gawk-2.11, replaced it's total dependence on floating point
with long integers, and tweaked a couple of things to get it to compile
under MINIX.  Now, it works great -- does anyone want it, and if so
should I post diffs or complete source?  It should work under any
MINIX with sizeof(int) = 4, and might just work with some effort
on PC MINIX.

C-news _almost_ runs.  /bin/sh needs help, as it can't run the C-news
configure script, so I generated the doit.* scripts on my VAX.  Bruce's
C compiler doesn't like to pass/return structures to/from functions,
so I've hacked dbz & friends.  C-news' fast stdio doesn't work with MINIX,
but I've brought up estdio2, which probably works at least as fast
(it is a very impressive package!).  putenv(3) seems broken (see below)
and dbz doesn't quite pass the regression tests yet.

putenv(3) (in lib/other/putenv.c) is broken.  It won't replace a
defined environment variable with a new value.  When replacing an old
definition of an environment variable with a new one, can (and should)
one do a free(3) on the old environment string before malloc(3) for
the new string?

Cristoph's cc68/386 gives a "memory fault: core dumped" now that
I've compiled with estdio2; it used to dump gibberish into the
.s files when compiled with the plain stdio.  Also, the "-DNOFLOAT"
option didn't seem to be completely implemented, as genfloat() and
gendouble() were left in genstmt.c and a couple of floating-point
related things were left in other files.  Has anyone developed
an out386_bcc.c?
