Mandrav, I noticed something regarding the configuration for MinGW.
It appears that CB doesn't actually detect the specific install of MinGW, it just assumes the defaults. Being organizationally AR on my PC, I installed MinGW into C:\Programming\MinGW, instead of the default C:\MinGW. When I went to doublecheck config, it showed C:\MinGW as my MinGW location.
If on install it's possible to scan the registry and preconfigure all the compiler options from actual install info, that may ease some of the problems.
