Subject: OCaml 3.10 native-code compiler doesn't build on Mac OS X 10.5.1

When attempting to "make opt" on my MacBook Pro running the new
10.5.1, the following error occurs:

gcc -I../byterun -DCAML_NAME_SPACE -DNATIVE_CODE -DTARGET_i386
-DSYS_macosx  -O -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT   -c -o

make: *** [runtimeopt] Error 2

I'm not sure if OCaml built in the initial Leopard release, 10.5.0,
because I didn't try installing it until after updating to 10.5.1
yesterday... but I do know it worked on 10.4. The bytecode compiler
builds and bootstraps just fine. Any ideas?
