Building synth with template all, using my native gcc:

$ gcc -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Debian 4.3.3-4'
--with-bugurl=file:///usr/share/doc/gcc-4.3/README.Bugs
--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --enable-shared

--target=i486-linux-gnu
Thread model: posix
gcc version 4.3.3 (Debian 4.3.3-4)

The fails with:

file or directory

Previous versions of gcc have had limits.h in /usr/lib/gcc

$ find /usr/lib/gcc/ -name limits.h                                  
/usr/lib/gcc/i486-linux-gnu/4.1/include/limits.h
/usr/lib/gcc/i486-linux-gnu/4.0.4/include/limits.h
/usr/lib/gcc/i486-linux-gnu/4.2/include/limits.h
/usr/lib/gcc/i486-linux-gnu/4.3/include-fixed/limits.h

but 4.3.3 does not. So the include_next <limits.h> at the end of
packages/isoinfra/current/include/limits.h fails.
