You were right, but using the mingw gdb results in the same problem, the
debugger cannot break into emacs:

C:\Users\deyke\emacs-build\subdir\work>gdb bin\emacs.exe 22936
GNU gdb 5.1.1 (mingw experimental)

This GDB was configured as "mingw32"...
C:\Users\deyke\emacs-build\subdir\work/22936: No such file or directory.
Attaching to program `C:\Users\deyke\emacs-build\subdir\work/bin\emacs.exe', process 22936

Then gdb hangs too, and cannot be interrupted by C-c.

For what is worth, process explorer shows the folloing threads in emacs
at that point:

!CreateThread+0x2e
!toascii+0x15d0
ntdll.dll!DbgUiRemoteBreakin
ntdll.dll!ConvertUiListtoApiList+0x276
ntdll.dll!ConvertUiListtoApiList+0x276

If I try to close the cmd window running the emacs build, I get:

"Windows cannot end thos program. It may need more time to complete an
operation."
