Two things about MISRA

  Not all of the MISRA rules can be automatically checked. MISRA is as mu=
ch about good practices as it is about enforceable standards.

  MISRA-C2 released about a month ago doesn't embrace C99 based C compile=
rs for an interesting reason. They claim that there isn't enough C compil=
ers out there that support C99 to justify recommending its use. It takes =
about 5 years for a standard to
drift on to center stage. Do the math. MISRA will continue to evolve and =
in general lead language standards in identifying appropriate programming=
 practices. This relationship between language standards and language cri=
tic is best seen in C99 which
incorporated many of MISRA=92s language specific deficiencies (like lengt=
h specific data types) into the C language standard.

A good read on this subject is Les Hatton's book "Safer C" .
