Ok. We don't actually compile anything in this directory, for reasons 
of historical laziness. Instead, what has happened is that we 
#include both the .h and the .c file in the 'parent' file in the 
fdesign directory. 

See, eg, sp_xyplot.c:

sp_xyplot.c:#include "spec/xyplot_spec.h"
sp_xyplot.c:#include "spec/xyplot_spec.c"

You should add your files to the EXTRA_DIST target in 
fdesign/spec/Makefile.am to ensure that they are distributed when the 
library is packaged as a tar file.

Well done.

Good. You've modified the generated Makefile it would appear. No 
problem, I can easily move this to Makefile.am.

See above.

Not today ;-)
