Summary: CPPFLAGS should not be aded to ldshard command

Initial Comment:
CPPFLAGS contains flags for the C preprocessor.  It has

no business being added to the ldshared command (this

is in sysconfig.py).  In fact, it may be harmful since

the ldshared command may well be ld with some flags

which typically does not understand cpp flags.



Irix where the ldshared command is "ld  -shared -all"

is a good example of where it is plain wrong to add

CPPFLAGS.

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.

OTOH, it also seems wrong that, on Irix, ldshared is "ld

-shared -all". ld should never be used directly.
