hello.c:1: error: bad value (corei7) for -march= switch
although, gcc451 --help=target -march=corei7 is successful.
gcc 4.4.4-10.fc13 (fedora 13 distribution) fails as well.
gcc451 -march=generic produces .s code with -march=core2
configured with:
../gcc-4.5.1/configure --prefix=/usr/local --program-suffix=451
--enable-threads \
--enable-languages=c,c++

--target-help is documented as alias for --help=target, but that doesn't
print this help - which means that the 2nd half of --target-help is from
the assembler and linker:
-mveclibabi= Vector library ABI to use
-mxop Support XOP built-in functions and code
generation
... end of GCC options, assembler options starting:
-Q ignored
-V print assembler version number
...
Linker options
==============
Use "-Wl,OPTION" to pass "OPTION" to the linker.
...
which means a proper header is missing for Assembler options.
