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