Subject: Cast the op_info value before applying bit shifts
X-Git-Tag: v0.40~6
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FVariable-Magic.git;a=commitdiff_plain;h=705dd25f6bac4f48abb98f534cc33e5f918b9faa

Cast the op_info value before applying bit shifts

Also move the opinfo member before the uvar one in the MGWIZ struct, as
it's used more frequently.
