The lower the number the more severe it is.

Short Description
Can't compile PostgreSQL 7.1.3 with Solaris 2.6

Long Description
Trying to compile postgresql under solaris 2.6 configure stops claiming about an unknown symbol "optreset". I wasn't able to fix the problem.

Sample Code
The last lines of config.log:
