Subject: Port: fix logging with C99 format specifiers on Mingw
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=994e8fa324cfb0d2eda1e087f9c84de0beba5572;p=deliverable%2Fbabeltrace.git

Port: fix logging with C99 format specifiers on Mingw

On Mingw when __USE_MINGW_ANSI_STDIO is defined, the printf family of
functions expects C99 format specifiers instead of the MSVC specific
ones. This should be reflected in the logging code to get proper display
of C99 types.
