Subject: Detect if glibc provides socklen_t and use that instead
X-Git-Tag: nfs-utils-1-0-9~33
X-Git-Url: https://git.decadent.org.uk/gitweb/?p=nfs-utils.git;a=commitdiff_plain;h=3172063ead6b99611d049a59938808a6358f48a4

Detect if glibc provides socklen_t and use that instead
of int in those cases which generate compile warnings,
e.g. the last argument of recvfrom().
