Author: hbelusca Date: Mon Aug 24 01:32:00 2015 New Revision: 68806 URL: http://svn.reactos.org/svn/reactos?rev=68806&view=rev Log: [KERNEL32] - Move some #defines where they belong; use ARRAYSIZE(...) macro where appropriate. - Use enumeration for the environment name types. - Fix BaseCreateVDMEnvironment so that we only convert the paths of TEMP/TMP, PATH, WINDIR and SYSTEMROOT env values to their short form, as done on Windows. To that purpose use the BaseGetEnvNameType_U helper. - Fix the loop that computed the needed new environment size. Needed for CORE-9773.
