Comment 1 for bug 1523739

Bug seems to be still existing in commit ad23dab (2016-04-27).

With master commit ad23dab (2016-04-27) i'm getting errors like these:
DockLibrary/DockItem.cs(34,12): error CS0234: The type or namespace name `Unix' does not exist in the namespace `Mono'. Are you missing an assembly reference?
DockLibrary/DockItemContainer.cs(33,12): error CS0234: The type or namespace name `Unix' does not exist in the namespace `Mono'. Are you missing an assembly reference?
DockLibrary/DockItemTitleTab.cs(33,12): error CS0234: The type or namespace name `Unix' does not exist in the namespace `Mono'. Are you missing an assembly reference?

With Pinta-1.6 i'm getting errors like these:
Actions/WindowActions.cs(30,12): error CS0234: The type or namespace name `Unix' does not exist in the namespace `Mono'. Are you missing an assembly reference?
...
Actions/AddinActions.cs(28,12): error CS0234: The type or namespace name `Unix' does not exist in the namespace `Mono'. Are you missing an assembly reference?

The autogen.sh / configure script probably needs some code to adjust this to the Mono version installed on the build system!

Found an easy way to workaround this here:

Looks like the Fedora people just use two "find ... sed ..." to fix this in their build system.

I Put those "find ... sed ..." commands in a script for you. (see attached Pinta-1.6_mono4-patch-script.sh)
It should work for Pinta-1.6 and master commit ad23dab (2016-04-27).

Be careful when running the script! It will change files without backup and without further notice!
