# Most systems allocate the *-shm file in 32KB trunks. But on UNIX systems
# for which the getpagesize() call returns greater than 32K, the *-shm
# file is allocated in page-sized units (since you cannot mmap part of
# a page). The following code sets variable $MINSHMSZ to the smallest
# possible *-shm file (i.e. the greater of 32KB and the system page-size).
