Ugh, top-posting. Reformatted.

I have attached the cygcheck file and a short program that I have copied
from a tutorial online. I am compiling it as shown here:
gcc shm_write.c -o shm_write
There are no errors or warnings when I compile, but whenI go to run, it
says "Bad system call".
Thanks for the help.
Uh-huh. You don't have "server" in your CYGWIN environment variable.
Try running your program as "CYGWIN=server ./shm_write". Please re-read
/usr/share/doc/Cygwin/cygserver.README for more details.
