AFAIK:
The switch -Wx,z is given to cc to hand the argument z to the
compile stage x. That means for the example above:
Hand "/usr/openwin/lib" to the stage l(linker)
=> a directory name as parameter (as reported by purify)
=> nonsense.
The correct command line option is "-Wl,-L/usr/openwin/lib" or
for runtime search "-Wl,-R/usr/openwin/lib" on solaris.
The gnu linker maybe silently ignores the strange stuff or
interprets the "-Wl,/usr/openwin/lib" in a non-standard manner.
