Details

Since PRCList is two pointers on a 32-bit machine sizeof(PRCList) == 8
while on a 64-bit machine (like Alpha) sizeof(PRCList) == 16.  The
problem is that SEGMENT_OVERHEAD is hard coded to 8 in nsIBuffer.h.
This brings up two questions:
(1) Will the code even work if SEGMENT_OVERHEAD is incresed to 16?
(2) Can it be set to some autoconf variable in place of a hard const.?

Good observation. Maybe this can be fixed by defining the constant as =
sizeof(void*) (although I don't know if you can use that expression in a
constant declaration). This issue will be moot soon anyway, since nsIBuffer is
going away soon (m10).
