Thank you very much.  I copied the include directory
to that path so that I now have:

          C:\Program Files\tcc\include and
          C:\Program Files\tcc\lib

yet  tcc still can't compile the program without the
-I and -L options.

What's more interesting, at my home PC tcc finds its
include and lib directories irregardless of where it
is located, as if it were looking them up relatively
to  the  location  of  the executable: I renamed its
parent directory (say, to TCC-2), and called it from
the root of the drive -- and it worked again.  I al-
so made sure that  it  was  the  local  (sibling  to
tcc.exe) include directory that was used by renaming
it.
