[gnuwin32 - Help] Flex - problems with switching input buffer

Hi, i'm trying to switch the buffer in FLEX (i'm pasring a script that uses
#include macros). I use GnuWin32 FLEX Ver. 2.5.4a-1 together with GnuWin32 Bison
Ver. 1.875-4.

I followed FLEX help file which has a sample code for switching buffers. My
problem is that when I switch the input buffer with:

yy_switch_to_buffer( yy_create_buffer( yyin, YY_BUF_SIZE ) );

FLEX continues to read from the _old_ buffer, no matter what I do, it just never
reads anything from the new buffer.

I was debugging it half a day and I can't find a reason why FLEX doesn't want
to read the new buffer, but just continues to read the old one.

yyin = fopen( yytext, "r" ); call seems to succeed btw.

Any help would be appreciated.

PS: I'm on WinXP using MSVC 2005 if that is relevant.
