Re: Compatibility problems with pgf 1.18

Hi Andreas,

this is, indeed, a broken compatibility issue. The \pgfnodeconncurve  
got kicked out in version 0.65 and when Mark and I fiddled in the new  
math code we forgot to check this super-old code...

I fixed this in the CVS. To fix it yourself without doing a checkout,  
find the file .../latex/pgf/compatibility/pgfcomp-version-0-65.sty.  
In this file, before the line

\let\pgfdegree=\pgfsincos

add the following:

\def\pgfsincos#1{%
   \pgfmathparse{#1}%
   \pgfmathcos@{#1}\pgf <at> y=\pgfmathresult pt%
   \pgfmathsin@{#1}\pgf <at> x=\pgfmathresult pt%
}

That should solve the problem.

If you find further similar problems please feel free to send them to  
me. Also consider using the pgf-user mailing list instead of the  
latex-beamer user list since this is not a beamer problem.

Best regards,
Till
