+
+V28 - unreleased
+ - fixes for MinGW build
+
+V27 - 11/22/2010
- Fixed REPOSITION-FILE FILE-SIZE and FILE-POSITION.
They used to use single precision offset. Now use double as specified.
- Delete object directories in Makefile clean.
http://code.google.com/p/pforth/issues/detail?id=4&can=1
- Fixed scrambled HISTORY on 64-bit systems. Was using CELL+ but really needed 4 +.
- Fixed floating point input. Now accepts "1E" as 1.0. Was Issue #2.
- - Fixed lots of warning and made code compatible with C89 and ANSI with -pedantic.
+ - Fixed lots of warning and made code compatible with C89 and ANSI. Uses -pedantic.
- Use fseek and ftell on WIN32 instead of fseeko and ftello.
-\r
+ - Makefile is now more standard. Builds in same dir as Makefile. Uses CFLAGS etc.
+ - Add support for console IO with _WATCOMC_
+ - Internal CStringToForth and ForthStringToC now take a destination size for safety.
+ - Run units tests for CStringToForth and ForthStringToC if PF_UNIT_TESTS is defined.
