Error "make[2]: *** [ghdl1] Error 4" while Building GHDL on top of a newer GCC 4.6.3

I see ghdl in the repositories:

Summary     : A VHDL simulator, using the GCC technology
URL         : http://ghdl.free.fr/
Licence     : GPLv2+
Description : GHDL is a VHDL simulator, using the GCC technology. VHDL is a language
            : standardized by the IEEE, intended for developing electronic systems. GHDL
            : implements the VHDL language according to the IEEE 1076-1987 or the IEEE
            : 1076-1993 standard. It compiles VHDL files and creates a binary that simulates
            : (or executes) your design. GHDL does not do synthesis: it cannot translate your
            : design into a netlist.
            :
            : Since GHDL is a compiler (i.e., it generates object files), you can call
            : functions or procedures written in a foreign language, such as C, C++, or
            : Ada95.

I suggest you look at the spec file the maintainers use for hints on how to compile it, if absolutely necessary.
