>Description:
===> Building for cryptopp-5.6.2
c++ -DCRYPTOPP_DISABLE_ASM -DNDEBUG -g -O2 -march=native -pipe -c wake.cpp
wake.cpp:1:0: error: bad value (native) for -march= switch
gmake: *** [wake.o] Error 1
*** Error code 2
>How-To-Repeat:
At least on an i386 box:

cd /usr/pkgsrc/security/crypto++
make
>Fix:
http://crypto-users.996303.n3.nabble.com/problem-compile-crypto-5-5-2-in-macosx-td868.html

says:

If I recall, GCC prior to 4.6 had a few [small?] issues with -
march=native.

So adding some extra logic around line 38 of GNUmakefile of crypto++
to check for gcc < 4.6 and/or 32-bit x86 should fix it.
(devel/cpuflags also generates -march native ...... won't work.)

or upgrade NetBSD's native compiler to gcc 4.6 or higher.
