Recent changes in CVS sources break build:
-lgcc /usr/lib/gcc/x86_64-pc-cygwin/4.8.2/../../../../lib/w32api/libkernel32.a

-Wl,-Map,cygwin.map
/usr/lib/gcc/x86_64-pc-cygwin/4.8.2/../../../../lib/w32api/libkernel32.a(dcnbs00754.o):(.text+0x0):

The existence of two snapshots generated from latest CVS would
imply that the error is on your end.

Or maybe it's a linux vs. windows build thing.

I think this is because I'm use win32-api from latest mingw-w64 trunk.

Alexey.

This must be a bug in latest mingw-w64. autoload.cc defines multiple
symbols which already exist in kernel32.dll. And all of these symbols
also exist in mingw-w64 libkernel.a:
$ grep kernel32 autoload.cc
LoadDLLfuncEx (CancelSynchronousIo, 4, kernel32, 1)
LoadDLLfunc (CreateSymbolicLinkW, 12, kernel32)
LoadDLLfuncEx (GetNamedPipeClientProcessId, 8, kernel32, 1)
LoadDLLfunc (GetSystemTimePreciseAsFileTime, 4, kernel32)
LoadDLLfuncEx2 (IdnToAscii, 20, kernel32, 1, 0)
LoadDLLfuncEx2 (IdnToUnicode, 20, kernel32, 1, 0)
LoadDLLfunc (LocaleNameToLCID, 8, kernel32)
$ strings /usr/lib/w32api/libkernel32.a | grep CancelSynchronousIo
CancelSynchronousIo
__imp_CancelSynchronousIo
CancelSynchronousIo
CancelSynchronousIo
__imp_CancelSynchronousIo
And the Idn symbols are already exported by the current w32api version:
$ strings /usr/lib/w32api/libkernel32.a | grep IdnToAscii
IdnToAscii
__imp_IdnToAscii
IdnToAscii
IdnToAscii
__imp_IdnToAscii
So I don't see why these two IdnToXXX functions should result in
problems but not any of the other kernel32 autoload symbols. For
completeness I tried to build ther Cygwin DLL natively on Cygwin, not on
Linux as usual, and it builds fine.
