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
compatibility is expected forward not backward.
New versions may have additional features that of course are not
available backward.

Marco
