Release Notes: This release fixes a bug in the -f option's support for #undef directives and improves portability to Windows.
Release Notes: The unifdef utility now supports simple cases in which macros expand to macros rather than directly to numbers, so it can use unaltered #defines from system headers more effectively. This release includes portability fixes for Windows.
Release Notes: The unifdef utility can now read #define and #undef preprocessor directives from auxiliary header-like files given with the -f command line option. You can use -f instead of or in addition to the -D and -U options.
Release Notes: This release can process multiple files with one invocation, and will include filenames on #line directives when appropriate. There is experimental support for Windows, including build instructions for MinGW and Microsoft Visual C. Feedback from Windows developers is welcome.
Release Notes: This release fixes the implementation of the -n option (insert #line directives) to work with the -o option (alternate output file). It greatly improves write error handling.
Release Notes: A little fix for overwrite mode.
Release Notes: Various trivial fixes were made, mostly related to build and release scripts.
