[Bug] non unix newlines in spec [sf#29]

[lsf37]

Reported by lsf37 on 2001-02-28 13:57 UTC
The new error reporting is a bit too eager: on Windows
and Mac platforms, JFlex doesn't recognize the %buffer,
%initthrow, %eofthrow, and %yylexthrow directives.
Reason: the \r line terminator is not parsed correctly
for these directives.

Workaround: Use the alternative form of the directive
for %initthrow, %eofthrow, and %yylexthrow, or set your
editor to use Unix \n line feeds.

This bug was reported by Hans Kratz and Thilo Goetz.

(fixed in 1.3.1)
