Author: Martin Storsjö <[email protected]> Committer: Martin Storsjö <[email protected]> Date: Fri Nov 30 11:16:58 2012 +0200 configure: Check for getenv When targeting the "windows store application" (metro) API subset (or the windows phone API subset), the getenv function isn't available. If it is unavailable, just define getenv to NULL. The check uses check_func_headers, since the function actually might exist in the libraries, but is hidden in the headers. The fallback is in config.h since msvc can't do -D defines with parameters on the command line, and it's used both within the libraries and the frontend applications (so a libavutil internal header wouldn't be enough).
