when minting stamps, i get almost a 50% failure rate:
$ hashcash -Xm foo
ERROR: requested 20 bits, reported 20 bits, got 1 bits using AMD64/x86 MMX Standard
1x2-pipe minter: "1:20:040915:foo::ryzM4fvR3J/CGAf9:00002xgx"
I get that, too, when I let gentoo compile hashcash. It ends up
building with these flags:
-O3 -march=pentium3 -pipe -fomit-frame-pointer -O3 -c
it works fine with the default flags for "make x86", namely
-DREGEXP_POSIX -O3 -funroll-loops -march=i386 -mcpu=pentium -mmmx
-D_REENTRANT -D_THREAD_SAFE -fPIC -c
This is all with gentoo (obviously), on a dual p3-1ghz.
===============
hhmmm... my build is with different flags (on freeBSD)...
# make x86
make "CFLAGS=-DREGEXP_POSIX -O3 -funroll-loops -march=i386 -mcpu=pentium -mmmx
-D_REENTRANT -D_THREAD_SAFE -fPIC " build
# make [generic]
make "CFLAGS=-DREGEXP_POSIX -O3 " build
...atom
