Ref : Bug #9469 HAVE_REALPATH not being checked : not yet fixed in TSRM?

System : 
AIX 3.2.5, apache 1.3.12, GNU Make version 3.76.1, gcc version 2.8.1

I configured and built php 4.2.2 in its own directory ok (my "gnu_make" is to differentiate from the IBM one) :

% ./configure  --with-apache=/usr/local/source/apache_1.3.12
% gnu_make
% gnu_make install
% cd ../apache_1.3.12
./configure --prefix=/www --activate module=src/modules/php4/libphp4.a

but ...

% gnu_make 

...

Do TSRM/tsrm_virtual_cwd.c/h (and others?) need to be updated with a check for HAVE_REALPATH.  It seems AIX 3.2.5 does not have realpath(), just like Win32 and BEOS ...
