| 32 Platform detection, specific defines and configuration. | |
| 33 The purpose of this file is to provide coherent platform and compiler | |
| 34 specific defines. So instead of defines like WIN32, _OpenBSD_ or | |
| 35 __GNUC__, one should use DC__OS_Win32, DC__OS_OpenBSD or DC__C_GNU, | |
| 36 respectively. | |
