687e3cf058 Ensure room before adding environment variable using set. Noted when running a subshell under NC. 
Bug left: we don't have a lot of environment space in that case (not the 160 minimum).

4a1ef4d3d7 Refine stack overflow and underflow for the fpu a bit. 
Overflow is still treated as Exit.
Underflow is ignored in release mode as it happens every now and then and doesn't seem to cause issues if ignored, thus restoring 0.74 behaviour.

94113a7362 Change multi_remain to repeat last parsed value for non-string types if the next value is empty and of the same type as the last. 
Use this to add an optional parameter to sensitivity which controls the y axis. When optional parameter is missing, x and y axis have the same value.
Change limits on sensitivity to allow for negative values so the Mouse Y-axis can be inversed. Similar to patch #276.

202bfa1155 New Drive type: overlay. 
When active, this drive redirects new and changed files to a different location.
The files in the overlay and normal drive are merged on startup and kept up to date when the game changes something. 
Files in the overlay are priotizedi, if they exists, above the normal files. 
The drive will switch to an overlayed version of the file on the first write! (Not when opening the file in write-mode).
The overlay is capable of creating missing directories.

With the help of DBOVERLAY files, the drive keeps track of files that are present in the normal directory but deleted by the game. 
All changes are preserved between sessions. 

Current design principles/limitations/requirements:
1) All directories that can be used for saving, must exist already in the base before mounting. (they will be created by DOSBox if missing in the overlay)
2) All filenames inside the overlay directories are UPPERCASE and conform to the 8.3 standard except for the special DBOVERLAY files.
3) To keep point 1 valid at all times, support for creating/renaming/removing directories has been disabled.

Thanks for the help GOG.
