Problem solved! RSI tech support pointed me to a variation of the
compile I hadn't tried yet and I can now compile calltest.
Here's a section of the RSI provided Makefile for calltest that defines
all of the linker flags.
LDFLAGS= -L$(BINDIR) -lidl -Wl,-rpath,. -Wl,-rpath $(BINDIR)\
/usr/X11R6/lib/libXm.a \
-lXp -L/usr/X11R6/lib -lXpm -lXext -lXt -lSM -lICE -lX11 -ldl \
-ltermcap -lrt -lm -lpthread
I changed the reference to libXm.a to refer to the libXm.so shared
object instead. Replacing /usr/X11R6/lib/libXm.a with -lXm was the
first trick. At this point I still couldn't compile with gcc 3.x. The
second trick was to use the gcc 2.96 compiler instead of gcc 3.x. Using
gcc296 and -lXm finally got me a clean compile and an executable that
wouldn't segfault.

I tried using gcc32, however I see the very same compilation error I had
before, except this time the error references gcc 3.2.3 instead of gcc
3.3.2. It would be nice if RSI would at least provide some
documentation that tells which versions of gcc, libc, etc they used to
compile.
/usr/bin/ld: calltest: hidden symbol `__fixunssfdi' in
/usr/lib/gcc-lib/i386-redhat-linux/3.2.3/libgcc.a(_fixunssfd i.oS) is
referenced by DSO
collect2: ld returned 1 exit status
make: *** [calltest] Error 1
I also tried using gcc296 but that brought up other errors relating to
libXm.a which is part of the openmotif library. I then downgraded the
openmotif and openmotif-devel packages and use the RSI provided RPMs
instead. I tried compiling with the RSI openmotif RPMs, but no matter
what I used (gcc296, gcc32, gcc) nothing got me any farther along in the
compile. The classic __fixunssdi error was still present. *Sigh*

I don't know if this is the problem, but FC1 uses the gcc 3.3 compiler. The
chances are, that if it works on RH9 but fails on FC1, that it's due to the
use of the 3.3 rather than the 3.2 compiler.
It might be worth installing the gcc32 package and trying again using gcc32
in place of gcc as the compiler.

A quick follow-up. If I add the -shared flag to my compilation
statement, I do not see the original error. However, there is still a
big problem because running ./calltest gives me a segfault. I have
LD_LIBRARY_PATH pointing to where it should,
/usr/local/rsi/idl/bin/bin.linux.x86.
Ideas?
