Unfortunately for latex209 calling \normalsize doesn't% work as this is optimized to do very little, so there \@normalsize should% be called. Hopefully this code works for all versions of LaTeX known to% mankind.  % April 25, 1996:% version 1.96: initialize \headwidth to a magic (negative) value to catch% most common cases that people change it before calling \pagestyle{fancy}.% Note it can't be initialized when reading in this file, because% \textwidth could be changed afterwards. This is quite probable.% We also switch to \MakeUppercase rather than \uppercase and introduce a% \nouppercase command for use in headers. and footers.% May 3, 1996:% version 1.97: Two changes:% 1. Undo the change in version 1.8 (using the pagestyle{headings} defaults% for the chapter and section marks. The current version of amsbook and% amsart classes don't seem to need them anymore. Moreover the standard% latex classes don't use \markboth if twoside isn't selected, and this is% confusing as \leftmark doesn't work as expected.% 2. include a call to \ps@empty in ps@@fancy. This is to solve a problem% in the amsbook and amsart classes, that make global changes to \topskip,% which are reset in \ps@empty. Hopefully this doesn't break other things.% May 7, 1996:% version 1.98:% Added % after the line  \def\nouppercase% May 7, 1996:% version 1.99: This is the alpha version of fancyhdr 2.0% Introduced the new commands \fancyhead, \fancyfoot, and \fancyhf.% Changed \headrulewidth, \footrulewidth, \footruleskip to% macros rather than length parameters, In this way they can be% conditionalized and they don't consume length registers. There is no need% to have them as length registers unless you want to do calculations with% them, which is unlikely. Note that this may make some uses of them% incompatible (i.e. if you have a file that uses \setlength or \xxxx=)% May 10, 1996:% version 1.99a:% Added a few more % signs% May 10, 1996:% version 1.99b:% Changed the syntax of \f@nfor to be resistent to catcode changes of :=% Removed the [1] from the defs of \lhead etc. because the parameter is% consumed by the \@[xy]lhead etc. macros.% June 24, 1997:% version 1.99c:% corrected \nouppercase to also include the protected form of \MakeUppercase% \global added to manipulation of \headwidth.% \iffootnote command added.% Some comments added about \@fancyhead and \@fancyfoot.% Aug 24, 1998% version 1.99d% Changed the default \ps@empty to \ps@@empty in order to allow% \fancypagestyle{empty} redefinition. \let\fancy@def\gdef \def\if@mpty#1#2#3{\def\temp@ty{#1}\ifx\@empty\temp@ty #2\else#3\fi} % Usage: \@forc \var{charstring}{command to be executed for each char}% This is similar to LaTeX's \@tfor, but expands the charstring. \def\@forc#1#2#3{\expandafter\f@rc\expandafter#1\expandafter{#2}{#3}}\def\f@rc#1#2#3{\def\temp@ty{#2}\ifx\@empty\temp@ty\else                                    \f@@rc#1#2\f@@rc{#3}\fi}\def\f@@rc#1#2#3\f@@rc#4{\def#1{#2}#4\f@rc#1{#3}{#4}} % Usage: \f@nfor\name:=list\do{body}% Like LaTeX's \@for but an empty list is treated as a list with an empty% element \newcommand{\f@nfor}[3]{\edef\@fortmp{#2}%    \expandafter\@forloop#2,\@nil,\@nil\@@#1{#3}} % Usage: \def@ult \cs{defaults}{argument}% sets \cs to the characters from defaults appearing in argument% or defaults if it would be empty.
