It looks like, on arm32 in <features.h>:
#ifdef _XOPEN_SOURCE
# define __USE_XOPEN 1
# if (_XOPEN_SOURCE - 0) >= 500
# define __USE_XOPEN_EXTENDED 1
/* ... */
And ptsname(), unlockpt(), grantpt() are under:
#ifdef __USE_XOPEN_EXTENDED
extern int grantpt (int __fd) __THROW;
extern int unlockpt (int __fd) __THROW;
extern char *ptsname (int __fd) __THROW __wur;
#endif
/* ... */
Fixes:
pty00.c:50:2: error: implicit declaration of function 'grantpt' [-Werror=implicit-function-declaration]
grantpt(fdm);
^~~~~~~
pty00.c:51:2: error: implicit declaration of function 'unlockpt' [-Werror=implicit-function-declaration]
unlockpt(fdm);
^~~~~~~~
pty00.c:52:14: error: implicit declaration of function 'ptsname' [-Werror=implicit-function-declaration]
slavename = ptsname(fdm);
^~~~~~~
pty00.c:52:12: error: assignment makes pointer from integer without a cast [-Werror=int-conversion]
slavename = ptsname(fdm);
