[gentoo-dev] [RFC PATCH 19/19] www-nginx/ngx-set-misc: new package, add 0.33

[Zurab Kvachadze <zurabid2016@gmail.com>]

The build system of this package automagically enables HMAC support
based on SSL functionality being enabled in the installed NGINX.

In order to enable this support independently, via a USE flag, a "hack"
is applied: only if GENTOO_USE_HMAC environmental variable and
preprocessor definition are defined, HMAC support is enabled.
