Portability problems fixed by Gnulib:
max_align_t
, which was added in C11.
wchar_t
.
NULL
macro that cannot be used in arbitrary
expressions:
NetBSD 5.0
Portability problems not fixed by Gnulib:
offsetof
macro that cannot be used in
arbitrary expressions:
Solaris 11 2011-11
This problem can be worked around by parenthesizing the
offsetof
expression in the unlikely case you use it with
sizeof
or ‘[]’.
