bug report

[Seb]

hi,

 

I'm a french student and I discovered two bugs while compiling with de GPP compiler:

 

- the 'delay()' function (dos.h) bug in my "fade_in" function while it is correct in another text-mode program.

 

- I had a bad result doing this:

 

  unsigned long offset = 640 * y + x;            --> ok

  unsigned long offset = y << 9 + y << 7 + x;         --> bad result

 

  I had to put up with:

 

  unsigned long offset = y << 9;

  offset += y << 7;

  offset += x;               --> ok

 

 

"gcc --version" returns:
