Hi Chris!

It works not yet right. The problem is:
it uses librarys which are builded to use crtdll.dll as c-runtime.

By this way it will be not correct to define __MSVCRT__  on compile time
and link it with msvcrt.dll
(and executable is linked with both crtdll.dll and msvcrt.dll - sometime
it can be 
working but somtime not (My project is not working by this way))
crt0,dllcrt0,gcrt0 -> CYGWIN1.DLL  linkage
crt1,dllcrt1,gcrt1 -> CRTDLL.DLL    linkage (gcrt1.o is not included in 
Cygwin-distribution, but can be obtained from MinGW-crtdll package)
crt2,dllcrt2,gcrt2 -> MSVCRT.DLL   linkage (MinGW-MSVCRT-package)

I  "downgraded" spec-file to use only crtdll.dll and it work like B20.1
(no MSVCRT) . It is attached.

Patch from Dale Goudey:
>  http://sourceware.cygnus.com/ml/cygwin/2000-06/msg00632.html
"How to add MSVCRT-support to Gygnus GCC" is a little of- topic:
to bring support for MSVCRT by this way  will be NESSECARY to put near the
whole  MinGW-MSVCRT-distribution into Cygnus-tree und there is
a lot of doubled headers. And modifing only "specs"-File cant work.

In GIMP for Win32 (sorry I have no URL) there is a document (I think it is
assembled from some Mumith-postings) how to  (was need to be recompiled with 
-D__MSVCRT__  )  build MSVCRT-support into GYGNUS natively (i.e. on place
of CRTDLL-support).

GDB is working now with CYGWIN-1.1.2. Thank you Chris.

Serge
