Simple profile suggests that pmc2c.pl is spending about 25% of it's
total execution time loading FindBin. The lib path use of FindBin::Bin
can be replaced with 'use lib qw( . lib ../lib ../../lib );' while the
other uses of FindBin::Bin will have be replaced by values that are
interpolated by genfile().
