forked from KolibriOS/kolibrios
k10temp:
- Fixed a bug with displaying incorrect temperature values. - Fixed memory leak (temporary failure of dlmalloc). - Small refactoring. - Use gnu99 to make empty functions with no return return 0. git-svn-id: svn://kolibrios.org@9827 a494cfbc-eb01-0410-851d-a64ba20cac60
