This is not the best way to detect this scenario, a better detection mechanism will replace this in the future

2012-10-12Windows: In-depth cleanup (see details)ChrisTX
-Fix x64 builds for Windows. Now all configurations compile. -Remove the non-working rebase stuff. -Remove the Windows fork hack and instead use FreeConsole() to emulate the behavior. This directly allows us to compile with ASLR, which is turned on now. -Remove the old IPC mechanism for the removed GUI. This is not needed anymore as the GUI wasn't ever supported on anything newer than 1.2 -Remove the WIN32/WINDOWS macros. _WIN32 is supported on all x86-based VC++ targets, so that's what we need. -Enable optimizations for release builds. -De-duplicate printf_c(), it was previously copy-pasted into colors.h for configure -Add the VC++ specific bad files in .gitignore -Disable PID writing on Windows. This is only making sense for *nix builds. -Replace the CPU usage retrieval with an algorithm analogous to the *nix behavior. Also supports separated now/total values. (Tested with a dummy busy loop - seems working) -Removed certain unused functions and variables -Remove stdint defines from the windows wrapper -Remove CRT debug alloc. This is a bad idea as it would define a macro to replace free which breaks builds. -Re-evaluated the warnings list, commented it. -Moved inspircd_config/_version to include/ to match *nix -Removed the creation of inspircd_se_config, as it isn't used at all. -Made non-git builds show as "r0" instead of "r" (thanks to @SaberUK for pointing this out) -Fixed up m_spanningtree's project paths. Now all configurations (debug/release x86/x64) have been tested and build properly. -Moved FindDNS out of the wrapper and matched its log behavior with *nix. (It's pointless having it in the wrapper after the recent slimming down) -Replaced random/srandom wrappers with a mechanism that tries to use Windows' Random API first is no SSL module is loaded. -Removed more old junk from support for compilers older than VC++ 2010 (we don't have project files for these, so compiling them would be hard anyways) -Removed the unused ClearConsole() -Removed unused includes from the wrapper. Also, do not include psapi.h here if we don't link psapi.lib. This should be done where appropriate. -Made inet_aton an inline function for increased performance -C4800, performance warning about bool forcing, resolved at all occurrences. -C4701, uninitialized variable 'cached', resolved at all occurrences. -dlerror() was migrated out of the wrapper for more thread safety (no global buffer being shared) and increased performance. -Removed the wrong CRT debug flags. This drains a lot of performance. -Removed the clock_gettime/gettimeofday wrappers -Replaced all TCHAR/ANSI mix-ups of functions with the correct respective function. -Added a block of C4355 for < VS2012 -Update project files for c870714

2012-03-20dns: more hardeningWilliam Pitcock
- don't trust rr.rdlength - don't accept replies we know are impossible for AAAA/A records - don't try to process record types we do not know about specifically (this behaviour just leads to disaster)
