First step towards windows debugging for OpenJDK

Yesterday I have installed WinDbg for the purpose of debugging openJDK (mostly around b118), I haven't started using it, will update how it goes

Make downgrade from 3.81 to 3.80

I was trying to build OpenJdk-b118 (for hotspot patch), for this I had to setup few things (as I never did it at my home system), then I realized that my blog had one state for MAKE just saying "Installed make: make version 'GNU Make 3.80'", which was not so simple as is sounds.
I had to struggle for an hour or more to just downgrade the make from 3.81 to 3.80, my mistake previously that I never made a note of it how to do it (downgrading from 3.81 to 3.80), but please note that this information is not complete as well, as I don't remember exactly from where I got the make 3.80 on to my office computer.
TO downgrade, I had to have copy to files one is "make.exe" with version 3.80 and the other is "cygintl-2.dll" (as I said I don't remember how exactly I got this two files, but hope this will be helping me or some other person struggling with downgrade).

argument parsing in Hotspot

Argument parsing in hotspot is done by the class "hotspot\src\share\vm\runtime\arguments.cpp", for example argument "-Xss" would be parsed in this (will be writing more on this when I go through it thoroughly).
