Yes, recent Fedoras AFAIK follow the MinGW-w64 port:
https://fedoraproject.org/wiki/MinGW?rd=SIGs/MinGW
https://fedoraproject.org/wiki/MinGW/CrossCompilerFramework
http://mingw-w64.sourceforge.net/

I have different results for gdb-7.7 with your patch on Fedora Rawhide
(=F-21pre) x86_64:

../../gdb/ser-tcp.c: In function 'net_open':
../../gdb/ser-tcp.c:162:19: error: storage size of 'hints' isn't known
struct addrinfo hints;
^
../../gdb/ser-tcp.c:196:30: error: invalid application of 'sizeof' to incomplete type 'struct addrinfo'
memset (&hints, 0, sizeof (struct addrinfo));
^
../../gdb/ser-tcp.c:205:3: warning: implicit declaration of function 'getaddrinfo' [-Wimplicit-function-declaration]
tmp = getaddrinfo (hostname, port_str, &hints, &result);
^
[...]

This is why I did start the unfinished/unsuccessful work on gdb/gnulib/ .

Does it mean the Fedora MinGW is broken? Which MinGW packaging have you used?

Thanks,
Jan
