ocaml @4.01.0 build failure with Xcode 5.1

[ats@…]

The ocaml port fails to build with Xcode 5.1. It fails as follows:

:info:build /usr/bin/clang -DCAML_NAME_SPACE -O -fno-defer-pop -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT    -c -o interp.o interp.c
:info:build clang: error: unknown argument: '-fno-defer-pop' [-Wunused-command-line-argument-hard-error-in-future]
:info:build clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

It appears that clang in Xcode 5.1 will treat unknown arguments as an error. This can be worked around by setting -Wno-error=unused-command-line-argument-hard-error-in-future or removing the unknown argument.

Here are a couple links I found which discuss this issue:
