[Click] Warnings when compiling latest version of Click on Linux 2.6.24.7

[David Zats]

Hi,

I get the following warning message when trying to compile click on Linux 2.6.24.7:

cc1plus: warning: command line option "-ffreestanding" is valid for C/ObjC but not for C++

The compilation does complete, but I was wondering if these warnings can be safely ignored.

Thank you!
