[PATCH 2/4] makedumpfile: cleanup non-standard ULONGLONG_MAX macros

Wang Nan wangnan0 at huawei.com
Fri Apr 25 21:07:07 PDT 2014


Macro ULONGLONG_MAX is non-standard, the standard way to defining
maximum limitation of unsigned long long is ULLONG_MAX, which is defined
in <limits.h> by C standard.

This patch replace all ULONGLONG_MAX to ULLONG_MAX.
