Workaround _ALL_SOURCE issue on AIX

[stevewan]

Summary

On AIX, many typedefs and struct definitions required by test-suite tests are only accessible when _ALL_SOURCE is set; however, setting this macro causes other side effects such as typedef redefinition. To fix this on AIX, we run test-suite with standard compatible mode (e.g., XOPEN_SOURCE=700), and use this patch to add the missing definitions to test-suite.

LGTM, with minor nit

MultiSource/Applications/d/d.h

79–81

nit: prefer the defined form, rather than relying on the macro value

MultiSource/Applications/viterbi/common.h

134–135

nit: same as above
