$ cat pox.f
      LOGICAL LL
      LL=.TRUE.
      IF (LL) THEN
        WRITE(*,*)'TRUE ',LL
      ELSE
        WRITE(*,*)'FALSE ',LL
      ENDIF
      STOP
      END


When compiled with:
$ /usr/local/gcc-3.3.3/bin/g77 -Wall -m64 -o pox pox.f
produces an executable that is linked thus:
$ ldd ./pox
        libg2c.so.0 =>   /usr/local/gcc-3.3.3/lib/sparcv9//libg2c.so.0
        libm.so.1 =>     /usr/lib/64/libm.so.1
        libgcc_s.so.1 =>         /usr/local/gcc-3.3.3/lib/sparcv9//libgcc_s.so.1
        libc.so.1 =>     /usr/lib/64/libc.so.1
        libdl.so.1 =>    /usr/lib/64/libdl.so.1
        /usr/platform/SUNW,Sun-Blade-100/lib/sparcv9/libc_psr.so.1
and produces this output:
$ ./pox
 TRUE  F

If compiled without the -m64 flag, and the environment variable LD_LIBRARY_PATH
is changed to /usr/local/gcc-3.3.3/lib (from /usr/local/gcc-3.3.3/lib/sparcv9)
then the output is correct:
$ ./pox
 TRUE  T
$ ldd ./pox
        libg2c.so.0 =>   /usr/local/gcc-3.3.3/lib//libg2c.so.0
        libm.so.1 =>     /usr/lib/libm.so.1
        libgcc_s.so.1 =>         /usr/local/gcc-3.3.3/lib//libgcc_s.so.1
        libc.so.1 =>     /usr/lib/libc.so.1
        libdl.so.1 =>    /usr/lib/libdl.so.1
        /usr/platform/SUNW,Sun-Blade-100/lib/libc_psr.so.1

../gcc-3.3.3/configure --prefix=/usr/local/gcc-3.3.3 \
