#6 can't build with non-GNU compilers

[Dimitri Papadopoulos]

Attempting to build dmucs-1.6.1 on Solaris using Sun's
latest Sun Studio compilers:
$ CC -V
CC: Sun C++ 5.8 Patch 121017-02 2006/04/19

I get this kind of errors:
"dmucs_db.h", line 224: Error: __func__ is not defined.
"dmucs_db.cc", line 290: Error: __func__ is not defined.
"dmucs_db.cc", line 301: Error: __func__ is not defined.
"dmucs_db.cc", line 321: Error: __func__ is not defined.
"dmucs_db.cc", line 386: Error: __func__ is not defined.

I don't think __func__ is standard C++, so it should be
protected by something like:
#ifdef __GNUC__

Actually __func__ is standard C99 but indeed, not standard C++.
