+Portability problems fixed by Gnulib:
+@itemize
+@item
+This function is missing on some platforms:
+HP-UX 11.00, IRIX 6.5, Solaris 2.6, mingw, Interix 3.5.
+@item
+This function may set the source pointer to NULL before NUL terminating the destination string on some platforms:
+OSF/1 5.1.
+@item
+This function updates the source pointer also if the destination argument is NULL on some platforms:
+HP-UX 11, OSF/1 5.1.
+@end itemize

+Portability problems not fixed by Gnulib:
+@itemize
+@item
+On AIX and Windows platforms, @code{wchar_t} is a 16-bit type and therefore cannot
+accommodate all Unicode characters.
