Support of a system call is not a function of GCC; it's a function of what's in your system's libraries. If Solaris's libraries support a function called fmemopen, then GCC will allow you to use it. However, if Solaris doesn't support it, then you're out of luck unless you find a third-party library of some kind with the functionality you're looking for. I just tried looking up a man page for it on Solaris 2.6 and 8, and didn't see anything. So, I'm guessing that you're probably out of luck...
