Watcom has extremely impressive customizable function calling controls. 
These are documented in the User's Guide shipped with the compiler, and are
described in connection with the "#pragma aux" functions.  Watcom
does support passing parameters using the CPU registers or the x87 stack on
a function by function basis, and also supports notification of which
registers may be modified by the function even if not used to pass
parameters.
