Windres here is following Microsoft's spec[1] for the ICON control 
statement and correctly rejecting this statement per spec. However, 
MS RC compiler seems to accept this, and a lot of the books have used 
this simply because it works (to be correct, it needs a ICON_STYLE 
parameter in addition to the 4 numbers you have there). 

I'll fix the incompatibility for the next release, but till then, you
can do the following (works for MS compiler as well):

 ICON "ABOUT1", IDC_STATIC, 7, 7, 21, 20, 0

where the last 0 just "or"s 0 to the list of current styles. FYI, this
is equivalent to:

 ICON "ABOUT1", IDC_STATIC, 7, 7, 21, 20, SS_ICON | WS_CHILD | WS_VISIBLE
