Conversion utility from lame Microsoft nmake to GNU make?

[John Freeborg]

We have hundreds of Microsoft nmake compatible makefiles and would very much like to dump them and convert whole hog to GNU make using the mingw version (esp. for the -j parallel build option).

 

Does anyone have any tool, notes, etc. on trying to automate this conversion a bit?  So far I think conditional syntax and tab character sensitivity for commands are on the list.  Those shouldn't be too bad.  / vs \ mess is not an issue I think since we are still planning on using cmd.exe as the shell.

 

Thanks,
