The _strdup usage in opal/util/basename looks like it was a product of Windows compatibility (see r11336), which we don't care about any more. Further, opal/win32/win_compat.h, which we sitll maintain for cygwin compatibility, #define's strdup to _strdup (which is what Microsoft wants you to use). So this old _strdup in opal/util/basename.c (and its corresponding check in configure.ac) should just be removed. This commit was SVN r32450. The following SVN revision numbers were found above: r11336 --> open-mpi/ompi@a28b025150 r32449 --> open-mpi/ompi@d5a3448b8b
