/* 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. */
