The radian functions were made one way, and now the degree ones some 
other way.  That's a bit unfortunate, even if the maintenance burden 
should be rather low.  What didn't work with regenerate.sh and 
Makefile.am?  Was it the autoconf/automake version?  I can see that you 
managed to regenerate Makefile.in.

The rest looks good.  I understand little of it though.
