It seems the canonical spelling is SIGCHLD. SIGCLD doesn't exist everywhere and it produces test failures under OS X:

http://www.python.org/dev/buildbot/all/builders/AMD64%20Leopard%203.x
http://www.python.org/dev/buildbot/all/builders/AMD64%20Snow%20Leopard%203.x

FWIW, this is what POSIX says:

“Some implementations, including System V, have a signal named SIGCLD, which is similar to SIGCHLD in 4.2 BSD. POSIX.1 permits implementations to have a single signal with both names. POSIX.1 carefully specifies ways in which conforming applications can avoid the semantic differences between the two different implementations. The name SIGCHLD was chosen for POSIX.1 because most current application usages of it can remain unchanged in conforming applications. SIGCLD in System V has more cases of semantics that POSIX.1 does not specify, and thus applications using it are more likely to require changes in addition to the name change.”
