Logged by:          Bo Chen

Description:

Hi, all

    Recently, We planned to use PostgreSQL for owner project, so we
retrieved the license of all PG source code. And the following files which
involve the GPL and perl copyright license. 
   We analyzes the comment of copyright in the file head. For files in
config dir, it seems our using is GPL exceptional. But I can't confirm my
understanding is correct or not?

    Best regards

config
    ax_pthread.m4
    check_decls.m4
    config.guess
    config.sub
    libtool.m4
    pkg.m4
