Subject: Only declare dMY_CXT when really needed
X-Git-Tag: v0.09~9
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2Fre-engine-Plugin.git;a=commitdiff_plain;h=9198b4f588644e22e005fe990c8321ce36a08375

Only declare dMY_CXT when really needed

Also wrap MY_CXT_INIT in a block, since it can be a declaration.
