Return to tools.fs CVS log

Up to [gforth] / gforth / kernel

Major change!
hash and search does not rely on each other.
context and voclink are now present in kernel.
words and marker can now defined without loading hash or search
marker went to extend.fs
word went to kernel/tools.fs
table goes to seperate file (at the moment)
glocals.fs and kernel/toolsext.fs are changed because of the change in the
wordlist-map-struct...
Attention: You can't recompile the code without new kernel-files!!!
