'Present But Cannot Be Compiled' with 6.0.0

[Jeff Donner]

Hi - I hit this problem when configuring on a Sparc Solaris 10 machine:

builder at sol10-sparc-43-build$ uname -a
SunOS sol10-sparc-43-build.some-company.com 5.10 Generic_142900-04 sun4v
sparc SUNW,SPARC-Enterprise-T5120 Solaris

configure: WARNING: sys/processor.h: present but cannot be compiled
configure: WARNING: sys/processor.h:     check for missing prerequisite
headers?
configure: WARNING: sys/processor.h: see the Autoconf documentation
configure: WARNING: sys/processor.h:     section "Present But Cannot Be
Compiled"
configure: WARNING: sys/processor.h: proceeding with the compiler's
result
configure: WARNING:     ## ssssssssssssssssssssssssssssssssss ##
configure: WARNING:     ## Report this to gmp-bugs at gmplib.org ##
configure: WARNING:     ## ssssssssssssssssssssssssssssssssss ##


... with compilation errors that may or may not help:

Thanks,
Jeff
