Commit: MSP430: Update prototypes in libgcc

[Nick Clifton]

Hi Guys,

  I am applying the following patch to update the prototypes in the
  MSP430 specific part of libgcc.  It adds missing prototypes for
  exported ABI functions, and it changes the prototypes for the
  arithmetic shift functions so that they explicitly take a signed
  char parameter.

Cheers
  Nick
