It seems like the -m32 has been lost in the tool chain. test.s is
32bit but the compiler seems to use the 64bit assembly driver...

#
# gdc -v -m32 test.s -o test -lm -lgcc -lpthread -lgphobos -L/where/ever/gphobos/is
# ./test
# > Hello
#

The above should succeed and print:
#

# Reading specs from /lib/libgphobos.spec

#

If that fails - most likely the "--32" in the "as" line is missing - it is
a GDC bug.

The following should always succeed:
#
# gcc -v -m32 test.s -o test -lm -lgcc -lpthread -lgphobos -L/where/ever/gphobos/is
# ./test
# > Hello
#
