* JBigI:

- Replace old non-PIC 62-bit linux libs (GMP 4.1.4 built in 2005)
        with PIC libs built with GMP 5.0.2. License is LGPLv3.
        Built by sponge with GCC 4.4.4, downloaded from
        http://sponge.i2p/files/jbigi/gmp-5.0.2/
        For 64-bit processors, both performance testing and
        the GMP changelog led us to use 5.0.2 for both the 32- and 64-bit versions,
        even though the files are twice as big.
        See http://zzz.i2p/topics/306 for discussion and test results.
        libjbigi-linux-athlon64.so was a 64 bit file; by the new naming standard
        supported by NativeBigInteger, it is now a 32-bit file and the
        64-bit one is libjbigi-linux-athlon64_64.so.
        All new 64-bit libs will have _64 appended.

 On Feb 27, 2006, jbigi-win-athlon.dll was copied to jbigi-win-athlon64.dll,
 as it should offer amd64 users better performance than jbigi-win-none.dll
 until we get a full amd64 build.

+================================
+
+Updates May/June 2011:
+  jcpuid:
+   - jcpuid.c updated to be compatible with -fPIC
+   - 32 bit libjcpuid-linux-x86.so updated, compiled with -fPIC.
+   - 64 bit libjcpuid-linux-x86_64.so added, compiled with -fPIC.
+   - See also javadoc and code in CPUID.java
+  jbigi:
+   - k62 and k63 are identical for all except windows; exception added to
+     NativeBigInteger to use k62 for k63. k63 files deleted.
+   - All 32 bit linux files updated with GMP 4.3.2, compiled with -fPIC,
+     except for athlon64 and pentium4, which use GMP 5.0.2.
+   - All 64 bit linux files updated with GMP 5.0.2.
+   - libjbigi-windows-athlon64.dll deleted, it was a duplicate of
+     libjbigi-windows-athlon.dll. NativeBigInteger now uses athlon as
+     a fallback for all 64-bit processors.
+   - Note that all new 64 bit files will use the _64 suffix. For example,
+     the old libjbigi-linux-athlon64.so file was 64 bit; now it is 32 bit
+     and the 64 bit file is libjbigi-linux-athlon64_64.so.
+   - The 4.3.2 files are half the size of the 5.0.2 files, and there was
+     little or no performance difference for 32 bit, so we are using
+     4.3.2 for 32 bit. For 64-bit processors, both performance testing and
+     the GMP changelog led us to use 5.0.2 for both the 32- and 64-bit versions.
