Hello,
I was compiling a C++ program using MYSQL database library and Ocropus
library.
It was running fine until I included <mysql.h> and <my_global.h>. Now
gcc gives warning like this,
---------
In file included from /usr/include/mysql/my_global.h:80,
from pdfOCR.cpp:19:
/usr/include/mysql/my_config.h:1234:1: warning: "THREAD" redefined
In file included from /usr/local/include/iulib/iulib.h:55,
from /usr/local/include/ocropus/ocropus.h:30,
from pdfOCR.cpp:14:
/usr/local/include/iulib/components.h:38:1: warning: this is the
location of the previous definition
------------
If I include the ocropus.h file _after_ including my_global.h, the
program doesn't compile at all and gives errors like this.

There are I think namespace issues. Please help fixing this.
Thanks
