Description Derrell Lipman 2007-05-04 09:49:26 UTC 
The configure test for whether readahead() is available, and the actual compilation of vfs_readahead.c which requires it use different flags.  If readahead() is available but is not explicitly declared, the configure test passes but the compilation fails.

If -Werror-implicit-function-declaration is going to be used during compilation, it should also be used during the configure tests so that configure will ignore features that will cause errors during compilation.
