More likely the 1.09 go32 I used.  The hacking to crt0 was
minimal, simply a call to a function that calls setmode().

I found it unsatisfactory to distribute a several meg package
when it could be packaged in less than 0.5 megs.  Actually,
pbmplus DOES support the name of the program on the command line.
Invoking it as 
ppmmerge tgatoppm.exe input.tga | ppmmerge ppmqvga.exe | ppmmerge
ppmtogif.exe > output.gif


would work.  However I did not know this at the time I ported the
package, and therefore is undocumented.  While perhaps DOSKEY
aliases *might* work (don't know if they work on just the first
command on a line, or any instance of a program invocation on a
line, such as after the pipe symbol), batch files will not work
since they don't allow piping.  4DOS may overcome some of these
problems.
