no `long long' type in C++

[Andreas.P.Priesnitz]

Hello!

When compiling a lex.yy.cc generated by flex 2.5.22 (using
FLEX_NEED_INTEGRAL_TYPE_DEFINITIONS !), I get warnings for the C-standard, but
non-C++-standard types "long long" and "unsigned long long" being used.

It is just a warning, so not a problem, but it seems (sorry, i've NO clue
about the flex internals) to be fixed by this patch to flexint.h (and
re-generating `skel.c'/`scan.c'?):
