solaris 9 warning

[Kurt J. Lidl]

I was running configure on solaris 9 (a fresh install from the
Solaris 9 update 7 -- aka the 09/04 version) on a netra 1125.

In particular, I was running the configure script for "readline-5.0",
and it popped out the following:

checking sys/ptem.h usability... no
checking sys/ptem.h presence... yes
configure: WARNING: sys/ptem.h: present but cannot be compiled
configure: WARNING: sys/ptem.h: check for missing prerequisite headers?
configure: WARNING: sys/ptem.h: proceeding with the preprocessor's result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to address@hidden ##
configure: WARNING:     ## ------------------------------------ ##
checking for sys/ptem.h... yes

Hence, this email.
