Added a file where difficulties using specific C functions can be

documented. The first one is mremap(), since its prototype differs
between Linux and NetBSD.

+# mremap
+#
+# The mremap function is not covered by POSIX, so operating systems are
+# free to define the function as they want:
+#
+# NetBSD: void *mremap(void *oldp, size_t oldsize,
+#			void *newp, size_t newsize, int flags);
+# Linux: void *mremap(void *old_address, size_t old_size,
+#			size_t new_size, unsigned long flags);
