There are some error in files associated with /usr/include/sys/select.h

following are 2 simple example files showing the problem:
test_bug.c & test_fix.c

When I use (without pointer):
        struct fd_set my_fd_set;
I get:

blackhole:~/src> gcc test_bug.c
test_bug.c: In function `main':
test_bug.c:12: storage size of `my_fd_set' isn't known
blackhole:~/src> 

I was expecting... this to work without error! :)

it's easily fixed by using the existing typedef fd_set:
        fd_set my_fd_set;

I suggest that the includes files should be fixed so the struct line
works, but I don't have any clue on how doing this.
I compiled exactly the same program (test_bug.c)  on AIX and Solaris
without any error.
I found this bug when trying to add the --enable-realtime option on the
amp package, which wasn't enabled (surely because of this bug) so I'll
report something about this there too.

thanks to add this bug to the report list and to transmit it to the right
persons (GNU?)

I'm using gcc version 2.7.2.3
