Problem with second %% in rules definition

[Patrik Luscan]

Hi there,
I have found litte inconvenience in flex-2.5.7 compiled from 
flex-snapshot-2002.05.19.tar.gz.
If I omit the second %% in my rules definition file, the produced C-code is not 
compilable, there is one redundand "#endif" at the end of the produced file.

This one produces bad code:
%%
.       { return *yytext; }


and this one is OK:
%%
.       { return *yytext; }
%%

With best regards,
Patrik Luscan.
