With current trunk I have this problem. This was introduced when the
asan was merged into trunk. I thought that I should not have to rebuild
any of the configuration files?
I am building like this:
$ cd gcc-trunk
$ svn update
At revision 193528.
$ cd ..
$ mkdir gcc-build
$ cd gcc-build
$ ../gcc-trunk/configure --prefix=/opt/gcc/gcc-trunk --enable-threads=posix --enable-checking=release --enable-languages=c,c++,lto
$ make -j8

To do so, use the procedure documented by the package, typically `autoreconf'.
