Actually, FindFirst is not OS dependant, but disk partition dependant.

I.e. searching on FAT disk in Unix should also be case insensitive,
because FAT is case-insensitive.
Searching on Ext2(3) or any other disk  case-sensitive partition
mounted in Windows should also be case-sensitive...

So the ideal solution is to create custom routines: MyFindFirst(
masks, attribs, dir, ForceInsensitive: Boolean);

1) detect if dir searched is case-sensitive
2) do search for all files (*), and check file name match manually.
