bison doesn't parse my include file

[Juergen Schumacher]

sorry for bothering anybody,

i am trying to c++ parse an include file with flex 2.5.35 and bison 2.3 on a 
mac os x snow leopard installation - everything without include file works 
perfectly.

my latest attempt was:

I|i          BEGIN(incl);

<incl>[ \t]*
<incl>[^ \t\n]+ {
        printf(yytext);
        printf("\n");

                       std::ifstream fin(yytext);
                       yy_buffer_state* my_buffer_state = 
yy_create_buffer(&fin, YY_BUF_SIZE);
                       yypush_buffer_state(my_buffer_state);
                       BEGIN(INITIAL);
                 }

i get the stream name correct, but receive an <<EOF>> immediately - instead of 
the parsed parameter values -
although i can read the stream via lex()...

am i stupid or do i miss some basic parser call...?

any help would be highly appreciated.

regards

juergen
