hi i'm using gcc in i686-pc-cygwin and building djvulibre library for target
i686-pc-mingw32 version of gcc in two platform is from latest git reprository.
and i'm using following configuration for djvulibre
./configure --prefix=/usr/i686-pc-mingw32 CC='gcc -mno-cygwin' CXX='g++
-mno-cygwin -I/usr/include/w32api' --target=i686-pc-mingw32
--host=i686-pc-mingw32
at link step, there is problem for new, delete operator function wrapper
(defined in cygwin.h #define CXX_WRAP_SPEC_LIST)
below are trial and error.

djvulibre is using its own new, delete operator function.
when we use -mno-cygwin flag for gcc with host i686-pc-cygwin,
stdcxx wrappers for cygwin must be disabled because of libcygwin.a is not
linked with it.
but, when building gcc for target i686-pc-cygwin ,
USE_CYGWIN_LIBSTDCXX_WRAPPERS and -mno-use-libstdc-wrappers seems to be
enabled.
then, CXX_WRAP_SPEC_LIST will be enabled although it must be disabled when
added flag -mno-cygwin. causing undefined symbol problem which i had.
but when linking with i686-pc-mingw32-g++, it has no undefined symbol problem.
because there is no --wrap argument.
please consider to fix this problem

This sounds more like a cygwin problem, not a GCC one.

It's a problem with the cygwin target-dependent linker spec.
The -mno-cygwin option is deprecated and scheduled to be withdrawn, so I was
tempted to close this as WONTFIX; in general, the future answer to all problems
with "-mno-cygwin" is going to be "use a real mingw-targeted cross-compiler
instead".
However removing it properly involves some code changes and stuff that I'd
really rather only do during stage1. I guess it would be such a simple and
safe fix to tweak the spec that I'm tempted to repair rather than remove it for
4.5. I'll spin up a patch.

I figure this is worth fixing in the ~22-hour window remaining before 2nd
April. The option although deprecated should not for preference be released in
a broken state, and since it worked in all previous versions (i.e. before I
added the libstdc++ wrappers) this is a regression. The fix should be really
really trivial:

I'll set the bootstrap going now. That'll leave me some time to test it this
coming lunchtime/afternoon/evening (UK time) and check it in long before
midnight.
Richard G., please speak up if you have any objection to this plan, if I
haven't heard anything from you by a few hours before the midnight deadline
I'll assume you're ok with it.

It looks reasonable - well, I don't know nothing about cygwin. But
it doesn't touch other targets, so if a cygwin maintainer is ok with
it I'm fine with it as well.
Richard.

bootstrapped, manual testing, and g++ testing now got far enough to verify the
critical testcases g++.old-deja/g++.abi/cxa_vec.C and
g++.old-deja/g++.brendan/new3.C aren't affected, which would be the place where
any problem in this change would show up. about to commit.
