After adding

CFLAGS.SunOS+= -D_XPG6

to Makefile, compilation breaks at

  CC     libgio_2_0_la-gsocket.lo
gsocket.c: In function 'g_socket_get_available_bytes':
gsocket.c:2391:32: error: 'FIONREAD' undeclared (first use in this function)
gsocket.c:2391:32: note: each undeclared identifier is reported only once for 
each function it appears in
gmake[4]: *** [libgio_2_0_la-gsocket.lo] Error 1

This is fixed by

#ifdef __sun__
#include <sys/filio.h>
#endif

in gio/gsocket.c. After that, compilation succeeds.
