Hello Khalid

Something is broken, either with my package for libcrm114.a or something 
else. When I set up pecl-crm114 I get this during the configure step:

This is a snippet from config.log

When I remove /usr/lib/libcrm114.a and use the bundled code all works 
well. As a side note I can add that Bill's simple_demo.c compiles and 
links well with the packaged library. Any idea what's wrong here?
