Return to configure CVS log

Up to [gforth] / gforth

*Added:
* configure.bat configures on MS-DOS machines
* io-dos.h provides IO for MS-DOS
* makefile.dos is a GNU make Makefile for MS-DOS
*Changed:
* Merged gray/gforth and gray/gray4, added conditional compilation for
  gray ports (gforth and bigFORTH first)
* added gforth recognising string in environment
* added interpreter support for images (starts now with magic)
* changed make rule for ds2texi, so that it can run with Messy-DOS
* added SAVESYSTEM in dumpimage.fs
* fixed bug in Makefile for big endian systems (->configure)
