My problem is that I use the Intel C++ compiler (version 10.1),

Have you tried asking Intel?
Yes, sort of. Yesterday, I started a thread about it on Intel's C++
compiler forum, which I assume is read by Intel employees as well as
users of the compiler. So far, there has not been any replies.
Here's my guess based on what -mmacosx-version-min does.
For the compiler:
-D__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__=1040
The /usr/include/AvailabilityMacros.h will then take care of turning
that into MAC_OS_X_VERSION_MIN_REQUIRED.
For the linker, if using the underlying ld or if using Intel's
compiler driver and it uses the underlying LD:
If linking an executable tell the linker not to add the default CRT
startup and instead add the pre-10.5 compatible crt1.o to the end of
the files list. This will make it link with the old crt1.o instead of
the new Leopard-only crt1.10.5.o.
There are similar steps if you're doing a dylib or bundle (they have
their own .o files equivalent to crt1.o).
