Error from Scan.pm and h2xs

I've gotten this same error with Oracle-OCI-0.02,0.03 and 0.04:

Scanning /data3/oracle/rdbms/demo/oci.h for functions...
Expecting parenth after identifier in `fd_set *__restrict __readfds'
after `fd_set *__restrict ' at /usr/local/share/perl/5.6.1/C/Scan.pm line 797.
h2xs failed at ./boot line 183


I have no idea where to begin looking at what the problem might be.

This is being built aginst Oracle 9i if that might be causing the problem.

Also using Perl 5.6.1

Thanks,

Steve Mayer
