Re: bison scan-code and flex-3.5.36

[Tys Lefering]

Hi,

Here is some more about a change in Flex scanners
from 'int' to 'yy_size_t' in the sf svn version.

Maybe Bison can do something with flex --header-file
output option and include it in flex-sacnner.h to get
a correct prototype for the get_leng.

http://flex.sourceforge.net/manual/Options-for-Specifying-Filenames.html#Options-for-Specifying-Filenames

`--header-file=FILE, %option header-file="FILE"'

instructs flex to write a C header to FILE.
This file contains function prototypes, extern variables, and types
used by the scanner.

The Flex skeleton change is here in revision 2.213 :

** various portability fixes that quiet compiler warnings on 64-bit hosts

Maybe this helps,
