Subject: [PATCH 3/6] Better handling for realpath() failures in
windows_make_so() on Cygwin
Fix a memory leak which would occur in the case when the result of realpath() is
greater than or equal to SO_NAME_MAX_PATH_SIZE.
Distinguish between realpath() failing (returning NULL), and returning a path
longer than SO_NAME_MAX_PATH_SIZE
Warn rather than stopping with an error in those cases.
Original patch from Tim Chick. Memory leak fix by Corinna Vinschen.
