That would be basic_istream/ostream.

With linker flags like --as-needed this becomes relevant even in the
shared case.

the operator tests for both existence and that the value is not null;
if the colon is omitted, the operator tests only for existence.

Please don't spread that further. CFLAGS (as well all CPPFLAGS, CXXFLAGS,
etc.) should always be reserved for the user to override any time. It it

You can use AC_DEFINE_UNQUOTED to define a macro to the result of a shell

Note that local is only valid in function context, so this will always
produce a failure.

Look at the generated Makefile.in: everything prefixed with
@ENABLE_GTK_DOC_TRUE@ is enabled (not commented out) when the condition is
true.
