Release Notes: A bug where #error and #warning directives were processed in the false branch of a conditional has been fixed.
Release Notes: This release improves cross-platform compatibility, and fixes a bug which caused gpp to crash when the same macro was defined twice on the command line. It now issues a warning on the use of deprecated command-line options. Installation instructions were added for Windows, Unix, and other systems. It is now packaged in a manner similar to most GNU programs, including a "configure" configuration/installation script suitable for Unix-like systems. There are minor changes (mostly typographical) to the manual.
