[svn-r26707] Port r26633 from trunk to 1.8 branch.
Tested: jam, koala, ostrich (h5committest)
Log from r26633:
Add -D_DEFAULT_SOURCE to CPPFLAGS on Linux systems. -D_BSD_SOURCE is deprecated
in recent versions of glibc, and -D_DEFAULT_SOURCE is the replacement. Keep
-D_BSD_SOURCE for now to support older systems. gcc will not issue a warning
about -D_BSD_SOURCE being deprecated when -D_DEFAULT_SOURCE is supplied as well.
Tested: jam, koala, ostrich (h5committest)
