        I've never used gunzip on anything but VMS and Unix, but I
just looked at it's DOC file, and it says that for MSDOS/WIN/NT the
default suffix is 'z'.  So, where the for-VMS code is setting 'gz'
in HTFWriter.c, you want to make it 'z', and where it's making the
suffix .txt- or .html- or .bin- you want to make it .tx or .ht or
.bi, so it ends up 8.2z.  Then on uncompression, change the 8.tx or
8.ht or 8.bi to 8.txt or 8.htm or 8.bin, and pass it to lynx for
rendering, or to the helper app.  If the helper apps care about
suffixes, you also want to change the .bin appropriately before
passing it to them.   If 8 is too small for distinguishing both
the process and the tempfile count for that process, maybe you
could get more room by creating a directory tree instead of just
an 8.3 filename.  And then get rid of that tree as well as the
tempfiles as part of the cleanup on exit.
