I am working on modifying a software package written to run in the older
SGI compiler environment. I have just had LOTS of problems that I have finally
nailed down to mixing old and new argument styles.

Seems you can't have newstyle argument lists (ANSI) receiving parameters
from old styles,non prototyped code.

I first tried to write all my new stuff in ANSI code, but it would
always get float (Coord) arguments wrong. Finally, I had to recode my
new subroutines in old C style arguments.

ANSI C:void MyNewSubroutine(Coord x,Coord y,Coord z)
{ do da, do that thing }

K & R 1: void TheOldWayToAvoid(x,y,z)
Coord x,y,z;
{ do da, do that thing }


It seems a bit much to be forced to 1)rewrite ALL the old code in ANSI
style headers or
2) Write new stuff with old style headers.

This is something that should be fixed. There is a lot of code out there that
needs work, and I should not have to write new stuff in old style c.
