Subject: Portability: Add hacks to define C++11 explicit N-bit type limits
X-Git-Tag: SQUID_3_5_4~13
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=43b3d2f93172b7ddba7281e9e14ffe07cddddfa9;p=thirdparty%2Fsquid.git

Portability: Add hacks to define C++11 explicit N-bit type limits

Add cstdint and stdint.h to libcompat headers and ensure that type limits
used by Squid are always available. Mostly this involves shuffling
existing hacks into the compat headers but the UINT32_* limits are new.
