Just a reminder to myself:

When using pkg-config on windows using mingw getting "Must specify package names" even when just asking pkg-config --help means:
DOES NOT WORK WHEN IN MSYS bin ONLY WORKS IN mingw/bin.

Also remember to add

export PKG_CONFIG_PATH=/lib/pkgconfig/
alias untar='tar -xvzf' 

to

/etc/profile

AND

rename sed.exe to 1sed.exe in /mingw/bin so your environment uses the mingw sed.

open source development tools are pretty much sucky when ported to windows. (GIT,pkg-config come to mind)

Oh, and why isn't there anywere an all-in-one installer for the gnu toolchain?
