Hi! Mingw32 contains in ws2tcpip.h:
static __inline char*
gai_strerrorA(int ecode)
...
#define gai_strerror gai_strerrorA
Thus, the following test in getaddrinfo.m4 will incorrectly return 'no':
AC_REPLACE_FUNCS(gai_strerror)
since the function isn't in any library.
How about the following patch? Tested on mingw32 and x86 debian in
Gnutls.
