NULL redeclared warnings?

[David Cogen]

I was using egcs for a while, now have gone to gcc 2.8. I am now getting
warnings "NULL redeclared" whenever I include <sys/param.h>, because its NULL
conflicts with gcc's built in NULL. Is this a known problem, and is there a
workaround?

I am using gcc 2.8.0, Sun-Solaris-Sparc.

Apologies for sending this to egcs, but every past question to gcc lists has
been ignored or ridiculed; not exactly helpful. Besides, this may have
migrated back into an egcs release by now, perhaps?

Thanks for any help.
