I believe this is the wrong approach.  Instead try setting
xm_defines=POSIX in the x86 & ppc darwin entries in config.gcc.
(That's how every other port fixes this issue.)

This will trigger an include of string.h in tsystem.h.  All target
files (should) include tsystem.h.  I checked and unwind-dw2*.c do, so
it should work.
