Subject: RT3984: Fix clang compiler warning on Mac OS X where %ld is used for uint64_t.
X-Git-Tag: OpenSSL_1_1_0-pre1~747
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=fb029cebaeb6b0dbdb05a26a515e38a52a3c0fa1;p=oweals%2Fopenssl.git

RT3984: Fix clang compiler warning on Mac OS X where %ld is used for uint64_t.

clang suggests %llu instead, but it isn't clear that is portable on
all platforms.

C99 and above define a handy macro for us, so we try to use that
definition and fall back to current definition if needed (though we
switch to 'u' for unsigned).
