Subject: MinGW does not know __int64, we can rely on int64_t provided by <stdint.h>
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1cb0d36b39f69367d63e940976faaa2c252763b4;p=thirdparty%2Fopenssl.git

MinGW does not know __int64, we can rely on int64_t provided by <stdint.h>

<stdint.H> is part of libraries which come with C99 compiler.

Fixes: #29548
