Cross-Compilation of MARX on 64 bit linux for 32 bit linux fails #11

When I try the following:

./configure --prefix=/nfs/cxc/a1/linux/opt/packages/marx-5.1.0/ --build=i686-unknown-linux-gnu "CFLAGS=-m32 -g -O2" "LDFLAGS=-m32"

then the make step fails with

[...]

It seems that the -m32 flag is passed to most gcc runs, but not to those that are compiled as stand-alone tools such as pset.

Workaround: Compile 32 bit version on a 32 bit system.

The most common scenario is that marx is compiled on the same system it's going to run on, so this is definitely not urgent.

Might be addressed automatically when I switch MARX to automake.
