C and stdin

why Can't i do this, compiler just hiss a fit
FILE*  fsomething={stdin};
and why is LINUX flex is spitting out information completely different form UNIX lex.  SAME FILE, same makefile  two different outputs,  one is 600 lines --- UNIX and the other is 1686--> linux
I got points to give, so I can award two-2-three folks so don't be SHY

flex is the GNU version of AT&T's lex.
To get rid of all the features/enhancements/improvements/performance of flex, and get a lex compatible output, use the -l option. Be warned, read    man flex  befor.

What kind of error are you getting with the stdin? I compiled both:

FILE *f = stdin;

and

FILE *f = {stdin};

with no problems. I'm using Mandrake 7.2/gcc 2.95.3...

Can you post the actual error you get?

lex and flex the chicken and the egg.
well "-l" by itself is not going to give you old standard , unix lex.  there are so many other option you will have to specify to go back.  Why don't you read on flex  and modify the input code so it will produce the output that you want.  

the idea of gcc is a new free for all compiler, so where did we go wrong?  who know.  in Theory FILE* should take the assignment just like U wanted, but  oh well.  I did not try it on my modifed RH 2.96, not standard release, but should work.
