Follow-up Comment #1, bug #16342 (project gnustep):

Jurij Smakov found the cause of the bug, as recorded in the Debian bug log. 
Apparently, the test in config/config.align.c for testing whether the
architecture needs shorts/ints to be word-aligned does not work properly, as
gcc optimizes away the assignments that are used to test it if "-O2" is part
of CFLAGS (which it is by default).

A fix is to force the compiler to make the assignments by, for example,
passing buf to an external function.  For example, the attached file (just a
3-line change from the original config/config.align.c) does this by passing
buf to puts.

File name: config.align.c                 Size:0 KB
patched config/config.align.c that forces the compiler to not optimize away
