#610 SDCC doesn't build with flex 2.5.31
When I try to build a CVS snapshot from today
(2003.10.18), I get the following error:
make[1]: Entering directory

The last version I built before that one was from
2003.10.02 and was built without problem.

It works with flex 2.5.4, so please do the upgrade.
I'm still investigating why it doesn't work with 2.5.31.
Unfortunately I don't have that version of flex.
Can you please send me SDCClex.c file, generated by:
flex -t SDCC.lex >SDCClex.c
so that I can take a look to it?

As far as I know, flex 2.5.31 is newer than flex 2.5.4.
Moreover flex 2.5.31 is the latest available version.
Please find attached SDCClex.c

The last flex vesrion, available from FSF
http://www.gnu.org/software/flex/ is 2.5.4.
The latest flex version is indeed 2.5.31 (thank you, Aurelien),
and can be found at http://lex.sourceforge.net/.
Flex 2.5.31 undefines yytext_ptr, so we have to define it
again.
Fixed in src/SDCC.lex 1.51
Aurelien, thank you again for your help.
