Actually, after testing with a*locally defined function*, i get as well 
some issues (not this one, others).
Let's try with linspace() that is a Scilab macro defined in 
elementary_functionslib:

// Scilab 5.5.2, without never previously run linspace()

-->function linspace(a,b,c)
-->  disp("this is my linspace()")
-->endfunction
Warning : redefining function: linspace                . Use funcprot(0) 
to avoid this message

-->linspace()
  this is my linspace() // OK

-->linspace(0,1,5)

  this is my linspace() // OK

-->elementary_functionslib.linspace(0,1,5)
  !--error 10000
linspace: Wrong number of input argument(s): 2 expected.
at line       9 of function linspace called by :
// KO: This syntax is accepted by Scilab's linspace. It should work 
here. = Scilab 5' bug
// If such a bug occurs for Scilab macros, it will likely occur also for 
ATOMS ones.
// Not really encouraging...

-->linspace(0,1,5)
  ans  =
     0.    0.25    0.5    0.75    1.
// Note : the previous call loaded the elementary_functionslib 
definition. It became and stands
// the current one. Since our locally redefined linspace() does not 
belong to a library, it no
// longer can be called...

Results of this tests are the same with Scilab 6-alpha1.

You may try building a library with your home-made local function.
An example of HowTo is given there, using genlib() and lib() :
http://fileexchange.scilab.org/toolboxes/365000/1.0#files

Then, you could use library-resolved calls.
