#88 stdint.h vs. older MSVS compilers

[xm]

Using of the C99 standard <stdint.h> causes that one cannot use older MS compilers (older than MSVS2010) to build the libjpeg-turbo without manual addition of the missing header files (e.g. from here: http://code.google.com/p/msinttypes).

tested with MSVS2005 on the libjpeg-turbo-code-1541-branches-1.4.x snapshot
(my latest working one was the libjpeg-turbo-code-1528-branches-1.4.x)

[DRC]

Fixed.
