teTeX mktexlsr problem

["Robert A McDougall" <McDougall at agecon dot purdue dot edu>]

mktexlsr misbehaves under Cygwin when $CYGWIN is unset or of zero length.

Typical symptoms are that the web2c filename databases don't get
made, and TeX, LaTeX etc. can't find their "fmt" files.

The error is in the test mktexlsr uses to decide
whether to use Un*x- or W*nd*ws-style path separators:

if test -z "$COMSPEC" && test -z "$ComSpec" || test -n "$CYGWIN"; then
  SEP=':'
else
  SEP=';'
fi

This is wrong because it's possible (and reasonable) to use
Cygwin without setting the $CYGWIN variable.  Better is:

if test -z "$COMSPEC" && test -z "$ComSpec" || test "x$OSTYPE" = "xcygwin"; then
  SEP=':'
else
  SEP=';'
fi

>From the mail archive, it seems likely that this was William
D. Kirby's problem
(http://sources.redhat.com/ml/cygwin/2001-04/msg00471.html).
Also that Kenta MURATA had the same problem, and proposed an
alternative solution, namely, unset $COMSPEC
(http://sources.redhat.com/ml/cygwin/2001-04/msg00476.html).
