One exception that I neglected to mention is that if
the flex option for reentrant code is used, YY_G,
the related structure, and the definitions of yyout
etc. that use YY_G may be required.  Often the code
that uses those will be in the .l file and won't need
a separate header, but on large projects it may be
convenient to separate the regular expressions and
the detailed implementation code by putting the latter
in a separate C file, in which case a header is needed
and the relevant items need to be visible. Generally,
though, that code won't be in the parser file either,
so the issue of clashes doesn't generally arise.
