Description Elliot Lee 2004-09-13 16:36:35 UTC 
rpmbuild --define 'distribution FooLinux'

macros file contains:
%distribution %{?distribution}%{!?distribution:Red Hat Linux}

This caused an infinite loop in macro expansion for your build of rpm.
Comment 1 Jeff Johnson 2006-01-21 12:13:45 UTC 
The loop was not infinite, recursion was detected and stopped at 16 levels.

There's little reason to test for macro being set within the macro expansion:

Doing
    %distribution Red Hat Linux
should override naturally with
    --define 'distribution FooLinux'
