PATCH 1/1 Use limits.h in Mini-OS for UINT_MAX, INT_MAX, and CHAR_BITS.

In Mini-OS, including the ANSI Standard header file limits.h causes warnings about redefinitions of UINT_MAX, INT_MAX, and CHAR_BITS. This patch eliminates the warnings by obtaining the definitions from limits.h.

Use limits.h in Mini-OS for UINT_MAX, INT_MAX, and CHAR_BITS.
