pthread coonfigure error

[mark_m]

Hi,
 
I would appreciate any guidance you could provide to me as it relates to the
following errors.
 
I am trying to install the ZThread-2.3.1 package on an AIX5.2 OS and I get
the following error:
 
checking pthread.h usability... no
checking pthread.h presence... yes
configure: WARNING: pthread.h: present but cannot be compiled
configure: WARNING: pthread.h: check for missing prerequisite headers?
configure: WARNING: pthread.h: proceeding with the preprocessor's result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to address@hidden ##
configure: WARNING:     ## ------------------------------------ ##
 
when I execute the 'make' command I get the following error the on the
pthread.h header file and I assume it is related to the error above:
 
/backup/gnu/usr/local/bin/g++ -DHAVE_CONFIG_H -I. -I. -I. -I../include
-I/backup/threads/ZThread-2.3.1/include/zthread
