  14  * We have an unfortunate problem in that, on Windows (both 32 and 64-bit), long is always 32-bit.
  15  * But on Linux (64-bit) long is 64-bit. Which leads to nasty situations where things that work
  16  * on Linux, fail on Windows.
  17  * So.....,
  18  * (1) introduce a typedef that will replace all usage of long in our codebase.
  19  * (2) to start with, that typedef acts that same as the long it replaces
  20  * (3) once the replacement is complete, this typedef will, on windows, become 64-bit.
  21  * (4) and once the fallout from (3) is fixed, we can start replacing tools::Long with things
  22  *     like sal_Int64.
