- 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.
- Update build docs
***net.i2p.util.NativeBigInteger, native part of the code****
See ../README for instructions.
Execute the build.sh script to produce jbigi library files optimized for a number of different CPU-types.

Linux-specific information:
===========================
Some linux distributions comes bundled with GMP.
Try 'locate lib/libgmp.so' to see.
If so, install the the libgmp3-dev debian package to get the libgmp headers.
Then export I2P=/path/to/your/i2p/install.
Then do 'build.sh dynamic'. This will do a quick build using your installed libgmp library
and then test it and the jbigi in your I2P installation to see which is faster.
If the new jbigi is slower, then run 'build.sh' (without the 'dynamic'), which will download
the libgmp library, build, and test that.
Windows-specific information:
=============================
The best way of building the jbigi dll's is to install Mingw {URL} and msys {URL}.
The combination of these two should be able to run the included build-scripts without modifications.
