>Description:

Packages linking to kpathsea produce this message:

[...]/print/web2c/work/.buildlink/lib/libkpathsea.so: warning: warning: 
reference to compatibility putenv(); include <stdlib.h> for correct reference

I don't remember offhand what the consequences of this are, and it may
not be serious, but it's in general unsafe...

>How-To-Repeat:

make

>Fix:

Track down where in kpathsea this is coming from and add necessary
standard header files.
