I'd like to see that. What I did see was it breaking :(

"Fatal Python error: (pygame parachute) Segmentation Fault

No matter what picture i tell it to use, gif,bmp, png, with or without
an alpha channel, with or without -convert-alpha, that is all that
happens.

The problem is, that 'long long' is the type that's being specified.
on gcc, at least, this means a integer >= 64bits big (I checked by
making a little prog printing sizeof(long long) (== 8bytes on my
system, sizeof(long) == 4, ie it's the same as an int.)), so either
the compiler is becoming confused (thinking a long was meant), or the
code is wrong.
