From article <4983@chinet.UUCP>, by dag@chinet.UUCP (Daniel A. Glasser):

Poor Dan Glasser has forgotten something:  the macro Mshrink includes
a dummy parameter, because the Gemdos call has an unused argument.

#define Mshrink(base,newsize) gemdos(0x4a,0,base,newsize)

Most macro files (including Atari's osbind.h) have this definition, but
you have to know it's there if you're setting up your own bindings.

This is a handy time to mention that the arguments to Fdatime are
documented wrong: the correct call is:

	Fdatime(timebuf,handle,wflag)
	int *timebuf;		/* pointer to two int's */
	int handle;		/* handle of file to change */
	int wflag;		/* 1 for write, 0 for read */
