I think the instructions for downloading the compiler is a bit hard to find on http://mingw.org/. Maybe the instructions on this page are those to recommend:
http://www.mingw.org/wiki/HOWTO_Install_the_MinGW_GCC_Compiler_Suite That page says there is an installer which they recommend for a beginner. Has anyone tried that? On Getting_Started, it says the automated installer has been deprecated and to use the manual installation instructions on the page. http://www.mingw.org/wiki/Getting_Started was what I used to install MinGW. (And for goodness sakes, I can follow it ...) The how to that Lennart mentions is referred to at the top of Getting_Started as `advanced installation instructions'. Ok, I will describe my actions by steps: 1. emacs src from CVS is ready. Huh? I'd score a copy of GNU Emacs via Bazaar. In fact that's what I've done, installed Bazaar on Windows and did bzr branch http://bzr.savannah.gnu.org/r/emacs/trunk 5. download coreutils-5.3.0.exe from http://gnuwin32.sourceforge.net/packages.html install it to C:\GnuWin32\ Why not MSYS from MinGW?
