Is there any tool in the Cygwin distro that allows to change subsystem

Same operation as e.g. 'editbin /subsystem:windows ...', but without the
need to have MS tools installed.

  Not yet, but it would make a great PTC for the new 'peflags' tool recently
discussed on this list.


If desired, I can later provide a patch that adds some 'peflags --subsystem=...'.


For now, I use a quick hack within the project's Makefile.
It first checks the header magic number and then:

$ echo -ne '\002\000' | dd bs=1 count=2 seek=220 conv=notrunc of=file.exe

:-)

This works because apparently all cygwin and mingw compiled .exe have the optional header at the same position.


Actually, I think THIS functionality, as well as the ability to set the
date field of a PE object as recently mentioned on the gcc list, is a
better fit for objdump.

I agree, but shouldn't this be a function of objcopy ?
