Compiling GMP 6.1.0:

Run the following commands in MSYS2:
step1) cd .. 
step2) cd gmp-6.1.0

Compiling GMP-ECM latest svn:

Run the following commands in MSYS2:

step1) cd gmpecm
step2) ./svn.bat
(This will download the latest svn of GMPECM. If this fails extract "c:\msys64\home\gmpecm-svn2916.7z"
to the folder "c:\msys64\home" folder using 7-zip. it will extract the subfolder "gmpecm".
Make sure you are still in the /home/gmpecm folder in MSYS2.)

step3) autoreconf -i

step5) make

Tuning parameters in step6, shut down other processes with significant cpu usage
step6) make ecm-params


	Extra tuning steps 6a-6c (Optional).
	step6a) make bench_mulredc
	
	Tuning parameters in step6b, shut down other processes with significant cpu usage
	step6b) ./bench_mulredc.exe >> ecm-params.h
	step6c) notepad ecm-params.h
		Mark the last 4 lines in "ecm-params.h" and cut (CTRL+X) and then mark the first
		4 lines and paste (CTRL+V), and then save (CTRL+S).

		You are replacing the preexisting tuning parameters in the first 4 lines with the
		last 4 lines just created by "bench_mulredc.exe".
		
		The 4 lines in question are those starting with:
		/* 0:mulredc 1:mul+redc_1  .....
		#define TUNE_MULREDC_TABLE .....
		/* 0:mulredc 1:sqr+redc_1  .....
		#define TUNE_SQRREDC_TABLE .....


step7) make check
step8) make install

The compiled GMP-ECM "ecm.exe" is now in the "C:\msys64\home\gmpecm" folder.
