xaa colors type

[Alessandro Camela]

Hi all , can anyone explain me because in this code ( /* $XFree86: xc/programs/Xserver/hw/xfree86/xaa/xaaFillRect.c,v 1.15 2001/12/13 18:01:51 eich Exp $ */) the pGC->fgPixel variable is passed as unsigned long int , instead the function pointer to FillSolidRects accepts the variabile int fg???   thanks...
