Subject: Fwd: Compatibility of binaries built with one version of cygwin with other versions of cygwin
From: Tom Kacvinsky <tom DOT kacvinsky AT vectorcast DOT com>

Question:  if I build an executable/shared library on one version of
cygwin, is it guaranteed to work on later versions of cygwin, or is
that not recommended?

I learned the difficult way that building on one version and running
on an earlier version doesn't work.  My binaries are based on C++
code, so there is a dependency on libstd++ and libgcc_s (using the
Linux names for these libraries) and that is where I think I was
getting burned.  I don't think it is a problem with cygwin1.dll

Thanks,

Tom
