I've pasted gzip-uuencoded versions of the two binutils patches below.
The first one, pe.em.patch-chuck.gz, adds  libfoo.dll.a, foo.dll.a to
the list of files to search for when hunting '-lfoo'. The second one,
pe.em.patch-mumit.gz, is an updated version of Mumits original
'--enable-auto-image-base' patch from
http://sourceware.cygnus.com/ml/binutils/1999-q3/msg00538.html. This now
applies cleanly to the version of binutils in CVS.

However, I was unable to test Mumit's patch because somewhere along the
road between 19990818 and 20000625, --shared broke. I'm getting the
following error, using the ==stock== cygwin binutils-20000625 ld.exe:

ld --shared -Bdynamic -e __cygwin_dll_entry AT 12 -o libz.dll
-L/usr/lib/gcc-lib/i686-pc-cygwin/2.95.2
-L/usr/lib/gcc-lib/i686-pc-cygwin/2.95.2/../../../../i686-pc-cygwin/lib 
--out-implib=libz.dll.a libz.def adler32.o compress.o crc32.o gzio.o
uncompr.o deflate.o trees.o zutil.o inflate.o infblock.o inftrees.o

-ladvapi32 -lshell32 -lgcc 

Creating library file: libz.dll.a
bfd_close libz.dll.a: Invalid operation

I have not been able to track this down although I've been trying for
hours. I do not know what is causing this error. Can anyone give any
pointers?

	* ld/emultempl/pe.em: institute the following
	search order for dynamic libraries on pei386:
	libfoo.dll.a, foo.dll.a (import libs),
	libfoo.dll, foo.dll (link direct to dll).
	Fall back to static lib (libfoo.a) if none
	of the above are found.
