Hi John,
thanks for the effort, however
something is not as expected on cygwin
 
$ file lib*       

libcruft.so:         PE32 executable for MS Windows
(DLL) (console) Intel 80386 32-bit
libcruft.so.3.1.51+: symbolic link to `libcruft.so'
liblibcruftso:       current ar archive

I will try to investigate why I have "so" instead of
"dll".
For the last "liblibcruftso" SONAME does not work 
if $(basename) is already "libcruft"

SONAME_FLAGS='-Wl,--out-implib=$(SHLLIBPRE)$(basename
$@)$(SHLLIB)'

should it be something like
SONAME_FLAGS='-Wl,--out-implib=$(patsubst
lib,$(SHLBINPRE)%,$@).$(SHLLIB)'


but I need to verify an prepare a patch

from config.log
