I get:

f951: error: unrecognized command line option "-march=native"

with

[karma] bug/timing% gfc -v -march=native -O3 time_trans.f90
Driving: gfc -mmacosx-version-min=10.3 -v -march=native -O3 time_trans.f90 -lgfortranbegin -lgfortran -shared-libgcc
Using built-in specs.
Target: powerpc-apple-darwin7

That is because -m options are target specific and -march=native
(really -mcpu=native) have not been implemented for PowerPC yet.
Though it could by reading the processor description bit.
