Hello Ansgar,

What does this switch do? When I do set the variable, it cannot even create the Makefiles:

[root at master1 gromacs-4.5]# ./configure --enable-shared --enable-double --enable-mpi --prefix=/cvos/apps/gromacs-4.5 
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking how to create a ustar tar archive... gnutar
checking for C compiler default output file name...
configure: error: in `/gpfs/ueasystem/escluster/gromacs-4.5':
