The order of testing in this old version of protcode.tex is wrong too 
(in the previous example > 14 is never tested because > 13 is true in 
that case). Here is a correct version which also does not need the >99 
test (because it is included in >14):

\def\adjustprotcode#1{%
     \needadjustprotcodefalse
     \ifnum\pdftexversion > 14
         \needadjustprotcodetrue
     \else\ifnum\pdftexversion > 13
         \ifnum \expandafter`\pdftexrevision > `g
             \needadjustprotcodetrue
         \fi
     \fi\fi
