\degreemacro defined? – Mico Apr 09 '13 at 04:21\it,\bf, etc. font macros are deprecated because they do not use the new font selection scheme introduced with LaTeX2e. Please use{\itshape ..},{\bfseries ..}or\textit{..},\textbf{..}instead. See Does it matter if I use\textitor\it,\bfseriesor\bf, etc. and Will two-letter font style commands (\bf,\it, …) ever be resurrected in LaTeX? for more information. – Torbjørn T. Apr 09 '13 at 06:10
