I found in tokenize.c entry
  {SGN_TOKEN, "sgn"}, /*Chris Huff jan 2001*/
then look for SGN_TOKEN in other files and found in express.c
  case SGN_TOKEN: /*Chris Huff "sign() function"*/
then forgot about sgn() and remembered sign()

but now I write:
  #version unofficial megapov 0.7;
  #warning concat(str(sgn(100),0,0),"\n")

and it won't work ???

I try remember ;-)
The reason is that both ("H" and "CH") have identical vocalizations in polish.
