[Rd] AIX testers needed

system("ulimit") of AIX gives back file block size.
A limit of memory is `ulimit -m'.
I made gcc-4.1.2 and made R-2.5.0+patched, but the problem did not happen.
$ gcc-4.1 -v
Using built-in specs.
Configured with: ../configure --with-as=/usr/bin/as
--with-ld=/usr/bin/ld --disable-nls --prefix=/usr/local1/gcc-4.1.2
--enable-threads --host=powerpc-ibm-aix22.214.171.124 --program-suffix=-4.1
Thread model: aix
gcc version 4.1.2
$ gcc-4.1 -print-multi-lib
pthread/ppc64;@pthread at maix64
$ export OBJECT_MODE=64
$ ./configure CC="gcc-4.1 -maix64" \
F77="gfortran-4.1 -maix64" \
CXX="g++-4.1 -maix64" \
