Compiler update breaks my ddd

I'm running Gentoo Linux on an opteron system.  I've just upgraded
compilers to
gcc (Gentoo 4.3.3 p1.0, pie-10.1.5) 4.3.3
GNU Fortran (Gentoo 4.3.3 p1.0, pie-10.1.5) 4.3.3

Gdb works just fine, but ddd does not seem to recognize that the source
files should be visible.  This is true in both C and Fortran.  In
Fortran I'm compiling with options

-ggdb -march=opteron -fimplicit-none -fno-f2c -fno-backslash\
 -funroll-loops  -ffpe-trap=zero,overflow,invalid -finit-real=NAN  -Wall
-Wextra

I'm usually running DDD 3.3.11.  But I just installed DDD 3.3.12-rc2 and
it has the same problem.  Any suggestions?  Thanks,
Fred
