Unguarded reference to AF_INET6 in lib/connect.c #6069
Description
There is an unguarded use of AF_INET6 in lib/connect.c:
Line 1337 in a326877
It prevented curl 7.72.0 from building out of the box on Solaris 2.6 as it has no IPv6 support.
After a quick workaround of replacing AF_INET6 with AF_INET the build completed.
Test results after workaround:
TESTDONE: 1103 tests out of 1106 reported OK: 99%
TESTFAIL: These test cases failed: 1700 1701 1702
TESTDONE: 1374 tests were considered during 660 seconds.
