compile error of 7.4 beta1 on AIX 4.3.3

I'm using xlc v 5.0 on AIX 4.3.3 to compile 7.4 beta1and got the error
below:
--------------------------------------------8<-------------------------------------------------------------------
xlc -O2 -qmaxmem=16384 -qsrcmsg -qlonglong -I../../../src/include
-I/usr/local/include/ -c -o hba.o hba.c
651 | hints.ai_flags = AI_NUMERICHOST;
.................................a..............
a - 1506-045 (S) Undeclared identifier AI_NUMERICHOST.
1237 | hints.ai_flags = AI_NUMERICHOST;
.........................a..............
a - 1506-045 (S) Undeclared identifier AI_NUMERICHOST.
-----------------------------------------8<-----------------------------------------------------------------------

it seems we should use NI_NUMERICHOST in AIX, for I check the
/usr/include/netdb.h
there can't find AI_NUMERICHOST, just NI_NUMERICHOST. change AI_NUMERICHOST
to NI_NUMERICHOST fixed the problem. But I don't konw the best way to
fix it.

the other problem is that I'll have to comment out the
#include "ldfcn.h"
in src/backend/port/dynloader.c to get compile continue.

and another platform problem:

---------------------------------------8<-------------------------------------------------------------------------

`/home/postgres/pgsql-7.4/postgresql-7.4beta1/src/backend/utils/error'
xlc -O2 -qmaxmem=16384 -qsrcmsg -qlonglong -I../../../../src/include

.....................a............................
a - 1506-052 (S) Duplicate case label for value 17. Labels must be unique.
-------------------------------------8<---------------------------------------------------------------------------

in /usr/include/errno.h:

-------------------------------------8<---------------------------------------------------------------------------
/*
* AIX returns EEXIST where 4.3BSD used ENOTEMPTY;
* but, the standards insist on unique errno values for each errno.
* A unique value is reserved for users that want to code case
* statements for systems that return either EEXIST or ENOTEMPTY.
*/
#ifdef _ALL_SOURCE
#define ENOTEMPTY EEXIST /* Directory not empty */
#else /* not _ALL_SOURCE */
#define ENOTEMPTY 87
#endif /* _ALL_SOURCE */
-------------------------------------8<---------------------------------------------------------------------------

the default ENOTEMPTY is equal to EEXIST, so the error above.
don't know how to make _ALL_SOURCE macro effect, so I can't send a patch
now.

and src/interfaces/libpq/fe-connect.c, still AI_NUMERICHOST problem.

and finally, the ecpg package:

-------------------------------------8<---------------------------------------------------------------------------

try to fix that later, report here first.

Thanks and regards
