Building gcc 4.6.3 (and older) outside of source tree, under solaris

[Jose-Marcio Martins da Cruz <Jose-Marcio dot Martins at mines-paristech dot fr>]

Hello,

I have problems compiling gcc-4.6.3 under Solaris 10 X86.

It seems to me that it's a bug, but I'm astonished that it hasn't yet be pointed out. Or I'm doing 
something wrong ?

I usually (for 10 years or more...) build gcc outside of the source tree. But I was puzzled because 
I couldn't do it for most gcc-4x...

Let's say :
* source code dir is at, say, /pathto/gcc-4.6.3
* build dir is at, say, /pathto/obj

Compile process stops at stage 3, saying that some files weren't found :
* ext/pb_ds/detail/resize_policy/hash_load_check_resize_trigger_imp.hpp
* ext/pb_ds/detail/bin_search_tree_/constructors_destructor_fn_imps.hpp

This are, in fact, symbolic links pointing to the source tree :

* 
/pathto/gcc-4.6.3/libstdc++-v3/include/ext/pb_ds/detail/resize_policy/hash_load_check_resize_trigger_imp.hpp
* 
/pathto/gcc-4.6.3/libstdc++-v3/include/ext/pb_ds/detail/bin_search_tree_/constructors_destructor_fn_imps.hpp

And, in fact the file names in the source tree are wrong : they have a bad extension : .hp instead 
of .hpp

I created the good files as symbolic links to the original .hp files and the compiling process ran 
smoothly...

Is this a bug ? Or I missed something ?

Thanks
