src/pmc/classobject.h: Why is it in this directory?

[James E Keenan]

File src/pmc/classobject.h was added very recently:

r18244 | jonathan | 2007-04-16 19:26:34 -0400 (Mon, 16 Apr 2007) | 1 line

I'm wondering why it was added in directory src/pmc/.  Previously, that 
directory held only files with names ending in .num or .pmc:

[parrot] 527 $ ls src/pmc/ | cut -d '.' -f 2 | sort | uniq -c
   1 num
  81 pmc

These were the 'pmc' files transformed by tools/build/pmc2c.pl into c 
files.  Is src/pmc/ the most appropriate location for a .h file?
