[Bug fortran/40873] -fwhole-file -fwhole-program: Wrong decls cause too much to be optimized away

------- Comment #3 from rguenth at gcc dot gnu dot org  2009-09-22 15:34 -------
Reconfirmed with current trunk.  If I move three to the top of the file I
even get

/tmp/ccGHHCCU.o: In function `main':
t.f90:(.text+0x1e): undefined reference to `three_'
t.f90:(.text+0x28): undefined reference to `three_'
collect2: ld returned 1 exit status

this makes -fwhole-file less useful than necessary.  LTO manages to fix up
the decls (thus, with -flto it builds and links fine with -fwhole-program).
