Updated README

Allow out-of-source builds. Quiet autogen.sh warnings.

Use AM_CPPFLAGS instead of INCLUDES. Use $(top_srcdir).

Add .gitignore to quiet git status.

Add project URL to AC_INIT.

Stop libtool from compiling files twice.

Have git ignore .deps/.

Don't override user CPPFLAGS.

(PIC options appear to be set already. INCLUDES already included.)

Clean configure.ac.

Make it closer to autoscan output.

Have autotools create INSTALL.

Use AC_MSG_FAILURE if GF-Complete not found.

Run autogen.sh.

(autoconf 2.69, automake 1.14.1, libtool 2.4.2)

Add some .gitignore files.

Fix configure cpuid unknown issue.

Move AX_EXT before AC_CHECK_LIB(gf_complete...) so that
-lgf_complete doesn't cause CPUID conftest compile to fail.

Don't check for internal gf_int.h header.

GF-Complete doesn't install it.

Quiet some autoreconf warnings.

INCLUDES is now AM_CPPFLAGS. Use single-argument AM_INIT_AUTOMAKE.

Remove some AC_REQUIRE whose conftest always failed.

Quiet configure warning.

(ARCH_64 doesn't appear to be used.)

CPUID "unknown" fix from upstream autoconf-archive.

Allow out-of-source builds. Use dependency tracking.

Remove config.h.in~.

Update ax_check_compile_flag.m4 from autoconf-archive.

Add .gitattributes.

Remove autoreconf-generated files.

Remove ACLOCAL_AMFLAGS.

See Automake 1.13 release notes.

Add files for 'make dist'.

Quiet some warnings.

getcwd() in <unistd.h>. Remove some vars.

Make headers compatible with C++.

Quiet some warnings.

Install additional headers in include/jerasure/.

Quiet some configure check internal failures.

Use new AX_REQUIRE_DEFINED instead of AC_REQUIRE, which expands
the macro and causes internal compile failure.

Fix file permissions.

Remove INTEL_SSE compiler defines.

(Can use HAVE_xxx or __xxx__ instead.)

Set default CFLAGS to '-g -O3 -Wall'.

Add more checks from autoscan.

Use AC_CONFIG_AUX_DIR([build-aux]).

Use processor time for timing.

Use clock() instead of gettimeofday().

Use common LDADD in Makefile.am.

Remove pre-autotools makefiles.

Ignore *.a. (Missed earlier.)

Quiet more warnings.

Document need for autoreconf -fi.

Removed README.nd and README.txt so changes don't need to be duplicated.

Remove autogen.sh.

Just use "autoreconf --force --install".
