  At least in Turbo-C, the function is definitely setargv(), and you can 
replace it without messing with the startup .obj file.  The option to have
wildcards expanded in the argv array just links in a different setargv(), and
if you don't need command line parameters at all, you can save some memory
in the executable by saying  setargv() {};
I have versions of setargv() written in both C and assembler  (distributed, I
think, before the current release of Turbo-C, which gives you the source for
setargv.asm), and it is quite easy to change the parsing and/or wildcard 
expansion.  I hacked mine to recognise [] as part of a wildcard pattern, so the
wildunix TSR program worked better.
