You don't need this anymore
  02-path-separator.patch
if you build net-snmp with
  export ENV_SEPARATOR=":"

And maybe now they'll accept a patch so that building on cygwin
doesn't require an evar.  I think  "gcc -mno-cygwin ..."  might still
have been supported when I tried to get it changed and the best they'd
do was an evar when building.


Is 06-winstub.patch necessary?  Necessary if all you're using is the
command line tools?
The changelog has this

    Cygwin: getnetent() / getnetbyaddr() build fix

    Recent versions of Cygwin have prototypes but no implementation for
    these functions. Hence avoid that the Cygwin prototypes conflict
    with the implementation.

In other words, if I'm using just the snmp{get,set} command line
tools, should I be applying this patch?

Thanks,
Lee

The current /usr/include/netdb.h definitions from cygwin-devel match the
prototypes under endnetent(3p) and netdb.h(0p) from man-pages-posix.
If you don't have cygwin-devel installed it shouldn't be an issue, and the
supplied implementation of the missing interfaces should match the POSIX specs:

Thanks for the tip, but I think I'll keep the patch for now.

I don't really know if it's required or not. I inherited the patch and 
it still applies correctly and tests work with it, so I'll leave it in.
