The UNIX free() function is required to work in the following situation:

for(s=head; s != NULL; s=s->next) free(s);

This means that free() is required to 'hold on' to the most recently
freed memory chunk until the next call to free(), or until the program
exits.  I suggest using AllocMem and remembering the length, or using
AllocRemember.  Either of these system-supplied memory allocators will
work find and will not link in all the code required to do malloc()
and free() from lc.lib.
