Indeed, the M4 -> newlib conversion is really rather broken in terms of
naming. Many actually clash (look for things like "300.fp" etc.. for
examples of bad naming).
The file-name above reflects the M4 macro invoked for that package.
74595_dil expands by calling "N 16 30", presumably a 16 pin 300 mil wide
footprint. I'm not sure why the macro is called "N".
I strongly suggest that no-one actually use the converted M4->newlib
output, and actually use the M4 ones (at least until the naming is
sorted out).
