#ifdef __FreeBSD__
# define _WITH_GETLINE
/* The MSG_DONTWAIT send(2) flag is non-standard, but widely available.
* However, FreeBSD doesn't define this flag when using POSIX feature
* test macros. Normally feature test macros are required to expose
* POSIX functionality, though FreeBSD isn't strict about this. In a
* sense it's technically correct to hide a non-standard flag when
* asking for strict standards compliance, but this behavior makes this
* flag impossible to use in portable programs, at least without this
* sort of special case.
*
* To get the prototype for getline(3), we need either a POSIX feature
* test macro or use the FreeBSD-specific _WITH_GETLINE macro. Since we
* can't use the former, we'll have to go with the latter.
