Subject: [PATCH 5/8] stdlib: fix arc4random return type to u_int32_t
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
It's documented to be u_int32_t and not uint32_t:
http://www.manpagez.com/man/3/arc4random/
This also fixes a major bug that stdlib.h includes stdint.h. Things
might go very wrong because stdint.h has conditional defines and
if stdlib.h is included before #define's for stdint.h we end up
missing things and breaking builds (e.g. openjdk).
