Thanks to DJ & other for the lame info:

"to make gmake you need gmake.exe" ...not in the distribution & 
"make" seg faults....thanks guys!

also the install script generates a mostly bogus makefile. So

after some hacking on the makefile I got make368 to make using

turboC make ver 2.0!

The bug I found (very quickly with gdb, thanks dj) : 

I use mks & the environment list may contain unset variables such 
as "~command.com". The following code in main.c is attempting to pick 
up stuff like "DJ=good_guy" and exspects the '=' character in every 
string. I added 2 lines below:

----------------------------------------------------------------------
make370 or older : main.c : 500 or so

  for (i = 0; envp[i] != 0; ++i)
    {
      register char *ep = envp[i];
vvvvvvvvvvvvvvvvvvvvvv
      if( *ep == '~' )
        continue;
^^^^^^^^^^^^^^^^^^^^^^
      while (*ep != '=')
       ++ep;

      /* The result of pointer arithmetic is cast to unsigned int for
     machines where ptrdiff_t is a different size that doesn't widen
     the same.  */
      define_variable (envp[i], (unsigned int) (ep - envp[i]),
               ep + 1, o_env, 1)
    /* Force exportation of every variable culled from the environment.
       We used to rely on target_environment's v_default code to do this.
       But that does not work for the case where an environment variable
       is redefined in a makefile with `override'; it should then still
       be exported, because it was originally in the environment.  */
    ->export = v_export;
    }
----------------------------------------------------------------------
Hummm! Doesn't  Unix do somthing similar in the environment var list?

However when I try & run either "go32 make" or make.exe via "strip make, 
coff2exe make".

Both complain of not enough memory to run!!! I have tried both under the 
mks shell or dos6.0 command.com shell (pigs up less memory) & I have 100Mb
of disk space....so virtual space should be no problem. Even make of
small programs break. Ideas? turbo c make or ndmake are starting to look
better! ?!@#

I was hoping to try the xlibemu stuff...doesn't seem to be any binaries
distributed there either. Baugh :~(

Thanks

Frank
