Ebuild patch for gnupg-2.0.9

Description Ryan Hill (RETIRED) gentoo-dev 2008-04-08 02:33:02 UTC
Heys.  There is a compilation error building gnupg-2.0.9 using GCC
4.3 and curl-7.18.1.  The error appears to be the result of this change
from the curl release announcement:

- added type checking macros for curl_easy_setopt() and
curl_easy_getinfo(), watch out for new warnings in code using libcurl
(needs gcc-4.3 and currently only works in C mode)

gpgkeys_curl.c: In function 'main':
gpgkeys_curl.c:303: error: 'typeof' applied to a bit-field

I've sent this to the gnupg-dev mailing list but I'm not sure if it went through.  I'll try again in a bit if it doesn't show up.

In the meantime, I don't know how to fix this correctly and haven't seen it reported elsewhere yet.  As you're probably more familiar with the codebase, let me know if you have any ideas.

Strange error!!! GCC error?

since the third param of curl_easy_setopt is boolean in this case (according to "man curl_easy_setopt") you can put a double not (!) to fix the compilation error.

> +curl_easy_setopt(curl,CURLOPT_SSL_VERIFYPEER,!!opt->flags.check_cert);

Better solution would be:
+curl_easy_setopt(curl,CURLOPT_SSL_VERIFYPEER, opt->flags.check_cert != 0);
