The files in question are created by configure itself with m4 macros
that output customised shell script/.pc files.  They contain @replaceme@
statements for substitution by config.status.  

They will always be present for config.status due to being created by
configure.  They are removed by distclean.

I don't think this is common (or good?) practice, but allows generation
of complex shell script as you can use m4 to make it at autoconf time
using e.g. m4_shift and recursion to generate the template.  I have also
been trying to get m4 to generate m4 code, to embed in and then output
from configure, but it got too messy!
