[fpc-pascal]Nul sub-routine

[IoDream]

          Hello to all,

   I would like to know if we can define a sub-routine to be nul, so that
when compiling this routine hold no byte at all. This is what a macro do,
but macros aren't implemented yet in FPC.
   This could be used, for example, in a C-like "assert" function that when
NDEBUG is defined the function is inserted, and when it isn't the function
waste no space. I include a DJGPP version of the function prototype.
   In other words; this is equivalent to the lines below, but is easier to
write, and looks much better in your source:
{$IFDEF NDEBUG}
  Assert(blabla);
{$ENDIF}

          Best Regards,
IoDream.
