Summary: g++ complains about mutable variables

Initial Comment:
While building a package for quantlib on  archlinux i got the following warning and error  

reference 'y2_' cannot be declared 'mutable' [-fpermissive]
../ql/math/interpolations/multicubicspline.hpp:277:34: warning: reference 'v_' cannot be declared 'mutable' [-fpermissive]
../ql/math/interpolations/multicubicspline.hpp:336:33: warning: reference 'y2_' cannot be declared 'mutable' [-fpermissive]
../ql/math/interpolations/multicubicspline.hpp:337:34: warning: reference 'v_' cannot be declared 'mutable' [-fpermissive]
../ql/math/interpolations/multicubicspline.hpp:337:39: warning: reference 'v1_' cannot be declared 'mutable' [-fpermissive]
../ql/math/interpolations/multicubicspline.hpp:337:45: warning: reference 'v2_' cannot be declared 'mutable' [-fpermissive]
make[2]: *** [BermudanSwaption.o] Error 1

After compiling with -fpermissive I could get it compiled but the  warnings are still there whenever the compiler encounters
the mutable variables.

Thanks for Quantlib

Looks like this issue was fixed by

http://quantlib.svn.sourceforge.net/viewvc/quantlib/trunk/QuantLib/ql/math/interpolations/multicubicspline.hpp?r1=17506&r2=17505&pathrev=17506

There are no other mutable references in that file, or anywhere else in
the source tree that I can find. This bug should be closed.

Message:
I will be interested to help; however, I currently do not have sufficient
computer space to install Fedora.

So if you have Fedora and can let me access via SSH/SFTP etc., I will be
happy to help tracing.

My contact is: <[hidden email]>, or, SourceForge account 'hyu9910'.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
