hmm ok checked out and it seems to work, but now it doesn't build a crt0.o

i crawled the configures and Makefiles in the sub-directories and it looks 
like this is the failure:
# ../newlib/configure --target=$target --prefix=$prefix -v
# make all | tee loggy
# more loggy
[snip]

i386-coff-ar cru lib.a locale.o
i386-coff-ranlib lib.a
make[3]: Leaving directory 
`/download/build_newlib/i386-coff/newlib/libc/locale'
Making all in sys
make[3]: Entering directory `/download/build_newlib/i386-coff/newlib/libc/sys'

make[3]: Leaving directory `/download/build_newlib/i386-coff/newlib/libc/sys'
Making all in reent

[snap]

the 'configuring in sys' showed no warnings or errors.
a quick look at the Makefile shows:

all-am: Makefile $(LIBRARIES) $(DATA)
where $(LIBRARIES) = $(SYSLIB) and $(SYSLIB) is:

#SYSLIB = \
#lib.a

$(DATA) in turn is defined as $(noinst_DATA) and $(noinst_DATA) is $(CRT0)
and $(CRT0) is empty definition...

do i have the proper tree? i downloaded 
ftp://sources.redhat.com/pub/newlib/newlib-1.9.0.tar.gz

thx,
