Looks like ifort on your system is generating 32-bit .o files by

configure:20653: gcc -O3 -DNDEBUG -fno-strict-aliasing -I. -c conftest.c
configure:20660: $? = 0
configure:20670: ifort conftestf.f conftest.o -o conftest
ld: warning: i386:x86-64 architecture of input file `conftest.o' is incompatible with i386 output

That's kind of surprising, I don't know why you would want to require
that bool and LOGICAL have the same values. We (and Intel) both do
bool like g++ does, but we each do LOGICAL to match the history of our
Fortran compilers. I never imagined anyone would think these should be
the same.
