sim: require a C11 compiler

With GDB requiring a C++11 compiler now, this hopefully shouldn't be a big deal. It's been 10 years since C11 came out, so should be plenty of time to upgrade. This will allow us to start cleaning up random header logic and many of our non-standard custom types.

 C Language Assumptions
 ======================
 
-The programmer may assume that the simulator is being built using an
-ANSI C compiler that supports a 64 bit data type.  Consequently:
-
-	o	prototypes can be used
-
-	o	If sim-types.h is included, the two
-		types signed64 and unsigned64 are
-		available.
-
-	o	The type `unsigned' is valid.
-
-However, the user should be aware of the following:
-
-	o	GCC's `<number>LL' is NOT acceptable.
-		Microsoft-C doesn't reconize it.
-
-	o	MSC's `<number>i64' is NOT acceptable.
-		GCC doesn't reconize it.
-
-	o	GCC's `long long' MSC's `_int64' can
-		NOT be used to define 64 bit integer data
-		types.
-
-	o	An empty array (eg int a[0]) is not valid.
-
-When building with GCC it is effectivly a requirement that
---enable-build-warnings=,-Werror be specified during configuration.
+An ISO C11 compiler is required, as is an ISO C standard library.
 
 "dump" commands under gdb
