Bug #7819: configure script doesn't recognize valid options
https://bugs.ruby-lang.org/issues/7819

Author: telemachus (Peter Aronoff)
Status: Open
Priority: Normal
Assignee: 
Category: build
Target version: 1.9.3
ruby -v: ruby 1.9.3p385 (2013-02-06 revision 39114) [x86_64-darwin12.2.0]


When configuring the latest version of Ruby, the configure script issues warnings about "unrecognized" but valid (?) build options.

To reproduce:

1. Untar the 1.9.3-p385.tar.gz
2. Give the following options to the configure script:

    ./configure --prefix=/usr/local/ruby-1.9.3-p385 \
            --with-openssl-dir=/usr/local \
            --with-readline-dir=/usr/local \
            --with-yaml-dir=/usr/local \
            --with-gdbm-dir=/usr/local \
            --with-libffi-dir=/usr/local

The result is this warning, both at the top and the bottom of the configuration output:

    configure: WARNING: unrecognized options: --with-openssl-dir, --with-readline-dir, --with-yaml-dir, --with-gdbm-dir, --with-libffi-dir

Based on discussion in irc and the results of the build, I think that the warnings are bogus. That is, those options are recognized and used in the build.
