[dpdk-dev] [PATCH] eal/windows: expose symbol rte_version

[William Tu]

When OVS inits, it calls rte_version to get the DPDK's version.
The patch fixes the error below by exposing rte_version symbol.
libopenvswitch.a(dpdk.c.obj) : error LNK2019: unresolved external symbol
rte_version referenced in function dpdk_init

I can see many functions not exported on Windows for no reason.
This includes the rest of the version API, but it's experimental,
so it's better to have this standalone patch for backporting
(since the patch it fixes is backported).
I'm going to restore other exports in a bulk patchset.

Applied, thanks.

Note: do not hesitate to ping when a patch is forgotten so long.
