appears to be responsible for the following stage 1 compile error
when compiling with lcc:

$ tail -20 $HOME/logs/test-latest-mars-lcc.out

gmake: *** [library] Error 2
+ echo 'building of stage 1 not successful'
building of stage 1 not successful
+ exit 1

The lines containing the error are C code of the form
"Buffer = (MR_Word) buffer", which is wrong now, since
the type of "Buffer" has changed from `MR_Word' to `MR_Char *'.

Pete, could you please fix this one?
