 Hi all,

 currently it is not possible to compile CrystalSpace 2.0 with gcc-4.7.1
 without the use of the "-fpermissive" switch. Here is the snippet from the
 gcc manual:

 {{{
 -fpermissive
     Downgrade some diagnostics about nonconformant code from errors
     to warnings. Thus, using -fpermissive allows some nonconforming
     code to compile.
 }}}

 The attached archive consists of 5 patches that clarify some calls to
 methods gcc-4.7.1 could not find by argument-dependent lookup. This means,
 that the compiler isn't sure about which exact method is meant.

 The log suggest a possible method (which is used if the -fpermissive
 switch is used), but please revise all substitutions, maybe they are
 wrong.

 If any of those substitutions is wrong, this would mean that compiling
 with the -fpermissive switch would result in broken code -- maybe
 impossible to debug.

 Here is a snippet from the logs, so you know what I did:

 {{{
