I maintain that CPPFLAGS has no business being part of
LDSHARED.  LDSHARED is used at link time only, and the C
preprocessor is not in any way involved in that step.

If you can come up with a better way of creating shared
libraries on Irix, be my guest.  The current way has served
us well for many years.  Looking at configure.in, it's
mostly gcc based systems that use gcc to do the linking of
shared libraries.
