Re:   Small-C V2 doc??

Yes, the HEX file seems to be the linked version of the sources.  I
was able to generate a new compiler from the sources by assembling
each, then using L80 to link them together.  I believe the cmmand
line I used was
       L80 RUNTIME,CC1,CC2,CC3,CC4,CALL,SYSLIB/S,CC/N/Y/E.

You'll get some undefined globals from this; they are references
in the header (at top of each CCx.MAC) that are externals declared and
never referenced.  They cause no problem, but I edited them out of my
local versions of the CCx.MAC files, just to keep it clean. Note that
these globals are for Hexdrix's SMALL-VM package, which is not used
unless expressly turned on when C is compiled.

As background, the CCx.MAC files are not the source for the compiler,
but rather the output of a version 1 compiler (running on a UNIX
machine).  Hence, to make any substantial changes to the compiler,
you'd need the CCx.C source files.  I haven't actually gotten as far
as recompiling the compiler on itself.         --Ron Fowler
