Re: [bug-libsigsegv] mingw failure

Hi,
First of all, let me express my deep gratitude for your patience in
explaining me these things; while they may seem trivial to you, I am
somewhat confused by them still and I would appreciate your further
help.

I am not sure this logic is correct.
I don't see why it matters whether the executables are run under wine or
natively.
It makes even less sense to me that you claim that the native (mingw)
executables should not be run under cygwin by configure.
I understand that, e.g., since mingw lacks symlinks, then configure code
which creates a symlink and then compiles a mingw program which tries to
manipulate it and fails, will have to conclude that the symlink
manipulation functionality is broken, which is just fine.
What's the problem?
