Yes, it helps! If I manually change that value to 1 and recompile it works.

I remember having htis topic already with Richard. I think the align 
test was tweaked

Richard, do you rember?

I upgraded this box to gcc 4.9 in the meanwhile, that's the only change 
I can think of.

See here:
configure:21236: checking short/int needs to be word aligned
configure:21255: gcc -o conftest -g -O2 -I/opt/csw/include 
-I/opt/GNUstep/Local/Library/Headers 
-I/opt/GNUstep/Local/Library/Headers 
-I/opt/GNUstep/System/Library/Headers -L/opt/csw/lib -R/opt/csw/lib 
-L/opt/csw/lib/ffi -R/opt/csw/lib/ffi 
-L/opt/GNUstep/Local/Library/Libraries 
-L/opt/GNUstep/Local/Library/Libraries 
-L/opt/GNUstep/System/Library/Libraries conftest.c -lnsl -lrt -ldl  
-lpthread -lz >&5

      ^
configure:21259: $? = 0
configure:21265: ./conftest
configure:21269: $? = 0
configure:21294: result: no

However, if I do "gcc config.align.c" and then run "a.out"

$ ./a.out
Bus Error (core dumped)

That's a big fat crash... so? what's wrong with the test? this is 
somehow a de-ja-vu.
