It is possible to add several commands via cygwin[1] or MinGW[2] into the windows commandline.
But this often doesn't work very well, since a few programs need additional files for compiling (like truecrack) which aren't included in MinGW or cygwin.
Nevertheless if you wan't to use the command "make" in Win7 you have to follow these 3 steps:
1) Download MinGW[2]
2) Install it and select besides the different compilers MSYS during the installation
3) After you have installed MinGW, add the path to the bin directory of your MinGW installation to the PATH environment variable. (or do it manually for testing, since changes on these variables need a restart to take place -> set PATH=C:\MinGW\bin;%PATH%)
4) Type "copy c:\MinGW\bin\mingw32-make.exe c:\MinGW\bin\make.exe" into your commandline
5) enjoy "make" ;)
One solution was to download a linux distribution, install it besides Win7 and then use the commands as recommended in the shell of this linux distribution.
That solution worked like a charm, the only "drawback" of that solution were the 6gb additional storage needed for installing the linux distribution.
