AIX because bos.rte.libc 4.3.3.88 includes a fix for a security bug that
greatly increases the amount of stack space used when calling functions
like gethostbyname. Thanks to Philip K. Warren <pkw@us.ibm.com> for the
fix.
1. Ports to older revisions of some Unix variants, e.g., BSD/OS 1.1,
OSF1 V2.0, etc., contributed by Brian Ostrom <briano@netscape.com>.
2. QNX port, also contributed by Brian Ostrom.
3. New macro USE_MACH_DYLD to represent the dynamic library loading
API of NEXTSTEP and Rhapsody.
4. On platforms whose socket address has the sa_len field, make a
copy of the PRNetAddr argument for PR_Bind, PR_Connect, and PR_SendTo
and set its sa_len before passing it to the system calls. This
fix is suggested by Bert Driehuis <driehuis@playbeing.org>.
5. Removed the unused field _lockf64 of struct _MD_IOVector. Not
every Unix platform has lockf, and the POSIX file locking API
uses fcntl.
for platforms that don't have 'long long'. In pr/src/Makefile and
lib/libc/src/Makefile, use single quotes so that we can avoid
using backslashes in double quotes (that doesn't work under
MKS shell).
