Subject: Parameterize WINT_MIN and WINT_MAX with __WINT_WIDTH__ to support arbitrary
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=bfec4b0274ba2b35da277feec495f2d1a6996baa;p=clang

Parameterize WINT_MIN and WINT_MAX with __WINT_WIDTH__ to support arbitrary
widths. This corrects the values of these definitions for MSP430 and PIC16.
