Warnings when generation documentation

[albert-github]

Crypto++ Documentation Issue Report

When generation the documentation a number of warnings are issued:

trap.h:56: warning: explicit link request to 'if' could not be resolved
trap.h:59: warning: explicit link request to 'endif' could not be resolved
trap.h:131: warning: explicit link request to 'if' could not be resolved
trap.h:133: warning: explicit link request to 'endif' could not be resolved

The line numbers are not completely correct, but on line 46 and 119 there is <pre> and on line 56 and 129 there is </pre> replacing these with \code and \endcode will remove the warnings and also show the code as a code block (with syntax highlighting and links).
