/* The only problem that has come up so far is __stpncpy being undeclared
below because <string.h> doesn't declare it without __USE_GNU. We could
work around that problem by just adding the declaration there, or by
eliding the inline functions in the absence of __USE_GNU. But either of
these would result in unoptimized calls (because no inline version of
__stpncpy will have been defined), and there may be other niggling
problems lurking. Instead we simply insist on _GNU_SOURCE for
compiling mig output; anyway, that better reflects the fact that mig
output requires nonstandard special support code not found elsewhere. */
