Subject: make define release_region conditional
X-Git-Url: https://git.sur5r.net/?p=groeck-nct6775;a=commitdiff_plain;h=f361ce9049e115e479fd0fb79a76e1ace1365b2f;hp=76d7b50c4a8c31f58cc42629105ea922addc4c32

make define release_region conditional

release_region is defined on RHEL6 although request_muxed_region isn't so generates a warning:

warning: "release_region" redefined

Making it conditional eliminates the warning.
