#warning directive

[Sergei Marochkin]

Can you add something like #error but for creating user warnings? And something like #pragma warning for adding new warnings and disabling/enabling existing.

This implemented in fork of Pawn 3.2.3664 by Zeex: https://github.com/Zeex/pawn/wiki/What's-new#pragma-warning

#warning

Print a user warning.

This works similar to the #error directive. For example, compiling a file
that contains

#warning Don't include this file

would result in

warning 237: user warning: Don't include this file

#pragma warning

This directive comes in two forms:

• #pragma warning (enable|disable) XXX

  Enable or disable a warning by its number.

  Useful for hiding unwanted warnings that otherwise cannot be fixed.

• #pragma warning (push|pop)

  Save or restore the list of currently disabled warnings.

  This can be used in conjuction with the previous form to toggle warnings
  for a piece of code:

  #pragma warning push
  #pragma warning disable XXX
  // some code here
  ...
  #pragma warning pop
