I tried to test 1.3.4 on available systems (ix86-pc-mingw,
ix86-SuSE-linux, powerpc-SuSE-linux, sparc-sun-solaris,
powerpc-apple-darwin and mips-sgi-irix) and I found a few problems:

On mingw, I'm unable to compile gnustep-base1.3.4 - make reports the
following:
...

Since I'm still unable to compile anything with nx-gnu-gnu on darwin5
which doesn't report "Bus error" or "segmentation fault", I produced a
working shared gnu-gnu-gnu library; these changes to target.make are
necessary:

And here are the final instructions for ffcall (before, it did't work for
the shared base library):
tar xf ffcall-1.8d.tar
cd ffcall-1.8d
configure
cd avcall
rm avcall-rs6000-sysv4.s
gcc avcall-rs6000.c -S -o avcall-rs6000-sysv4.s
make
make install-lib
cd ../callback/trampoline_r
ln -s trampoline_r.h.in trampoline_r.h
rm cache-rs6000-sysv4.s tramp-rs6000-sysv4.s
gcc cache.c -S -o cache-rs6000-sysv4.s
gcc trampoline.c -S -o tramp-rs6000-sysv4.s
cd ../vacall_r
rm vacall-rs6000-sysv4.s
gcc vacall-rs6000.c -S -o vacall-rs6000-sysv4.s -DREENTRANT
make
gcc -c misc.c -fno-common
ar cru .libs/libvacall.a  vacall.o misc.o structcpy.o
cd ..
make
make install-lib

To compile gnustep-base, the following has to be changed in NSDecimal.m:

#include <math.h>
#if !defined(__APPLE__) || !defined(GNU_RUNTIME)
#include <ctype.h>
#endif
#include <Foundation/NSDecimal.h>
#include <Foundation/NSString.h>
#include <Foundation/NSDictionary.h>
#include <Foundation/NSUserDefaults.h>

Only bundles don't work:
The test for global constructors in configure fails and running
Testing/obj/nsbundle reports:
...
Retreiving principal class...
Error (objc-load): Cannot initialize dynamic linker
* ERROR: Can't find principal class


For irix6.5, changes have to be made in target.make:

#
# Target specific libraries
#
...
ifeq ($(findstring irix, $(GNUSTEP_TARGET_OS)), irix)
  ifeq ("$(objc_threaded)","")
    TARGET_SYSTEM_LIBS := $(CONFIG_SYSTEM_LIBS) -lm
  else
    INTERNAL_CFLAGS = -D_REENTRANT
    INTERNAL_OBJCFLAGS = -D_REENTRANT
    TARGET_SYSTEM_LIBS := $(CONFIG_SYSTEM_LIBS) $(objc_threaded) -lm
  endif
endif

(This helps, if gcc supports posix threads)
And instead of two sections called IRIX, the following one is needed
(Bundles, static and shared libraries work on Irix6.5):

####################################################
#
# IRIX
#
ifeq ($(findstring irix, $(GNUSTEP_TARGET_OS)), irix)
HAVE_SHARED_LIBS        = yes
STATIC_LIB_LINK_CMD = \
        (cd $(GNUSTEP_OBJ_DIR); $(AR) $(ARFLAGS) \
        $(VERSION_LIBRARY_FILE) `ls -1 *\.o */*\.o`);\
        $(RANLIB) $(VERSION_LIBRARY_FILE)
SHARED_LIB_LINK_CMD     = \
        (cd $(GNUSTEP_OBJ_DIR); $(CC) -v $(SHARED_LD_PREFLAGS)
$(SHARED_CFLAGS) -shared -o $(VERSION_LIBRARY_FILE) `ls -1 *\.o`
$(INTERNAL_LIBRARIES_DEPEND_UPON) $(SHARED_LD_POSTFLAGS);\
          rm -f $(LIBRARY_FILE); \
          $(LN_S) $(VERSION_LIBRARY_FILE) $(LIBRARY_FILE))

SHARED_CFLAGS     += -fPIC
SHARED_LIBEXT   = .so

HAVE_BUNDLES    = yes
BUNDLE_LD       = $(CC)
BUNDLE_CFLAGS   += -fPIC
BUNDLE_LDFLAGS  += -shared
endif

# end IRIX

Unfortunately, subproject.o in subdirectory Additions will not be linked
by make and I only found a workaround:
cd gnustep-base-1.3.4/Source/Additions/shared_obj/mips/irix6.5/gnu-gnu-gnu
(or cd
gnustep-base-1.3.4/Source/Additions/static_obj/mips/irix6.5/gnu-gnu-gnu)
ld -o subproject.o -r GSMime.o GSXML.o
cp subproject.o ../../../../../shared_obj/mips/irix6.5/gnu-gnu-gnu
(or cp subproject.o ../../../../../static_obj/mips/irix6.5/gnu-gnu-gnu)

Does anybody know how to solve this problem, which also affects cygwin?

linux and solaris seem to work.
