Trivial remark. Not really necessary to do the #ifdef. #undef works fine
if pr_fmt has not been defined.
Really? I thought it would give a warning then, but couldn't test it
since it was defined for me.

I made a little test program to confirm my thought, before sending my
previous email. Retried compiling with '-W -Wall -ansi -pedantic' and no
complaints about the #undef.
