[Rd] AIX 5.3 --enable-R-shlib make error with R-2.7.1

[Jagat.K.Sheth at wellsfargo.com]

Using AIX 5.3 and gcc-4.2.1 for building R-2.7.1 with the following
configure flags

OBJECT_MODE=64
CC="gcc -maix64" 
CXX="g++ -maix64" 
F77="gfortran -maix64" 
FC="gfortran -maix64" 
CFLAGS="-g -O3" 
CXXFLAGS="-g -O3" 
FFLAGS="-g -O3" 
FCFLAGS="-g -O3" 
LDFLAGS="-L/$HOME/usr/local/lib/ppc64 -L/$HOME/usr/local/lib" 
CPPFLAGS="-I/$HOME/usr/include" 
./configure --disable-nls --without-iconv --prefix=$HOME/usr/local
--enable-R-shlib 

After a successful configuration, the make stops with the following
error on this system

make[3]: Entering directory

On the other hand, no problems on this system with the above
configuration building R<=2.6.2. Can also successfully build R-2.7.1
here without --enable-R-shlib.

Will be glad to experiment or provide more details if needed anytime. 

Thanks,
Jagat
