Re: [Mingw-cross-env-list] CGAL example build fails + fix

[William]

Hello,
Here is the methodology to modify a patch :

there are files src/cgal.mk and src/cgal-1-fixes.patch, the second being 
the patch file.

import the patched directory in gits/ :
# tools/patch-tool-mxe import cgal

then edit the files, you can use git add, git commit, ...

then make a patch from that :
# tools/patch-tool-mxe export cgal

now try to compile :
# make cgal

now you can submit the updated patch!
