Comment (by emcrisostomo):

 Flex upstream provided an answer:
 https://github.com/westes/flex/issues/486#issuecomment-850868673

 To make a long story short, a more ambitious restructuring of {{{flex}}}
 is in progress, and it'll take time.

 According to upstream's suggestion, tt seems like the easiest thing to do
 would be copying {{{FlexLexer.h}}} in the build directory, patching it,
 and the overriding the relevant include dir, which is fortunately already
 being taken care of in {{{configure.ac}}}:

 {{{
 AC_ARG_WITH(flexlexer-dir,
     [AS_HELP_STRING([--with-flexlexer-dir=DIR],
                     [location of FlexLexer.h.])],
 }}}
