[fpc-pascal] Single or Double

[Marcel Martin]

Hello,

I need to know *at compile time* whether the type Real is
Single or Double. Currently, I use this

{$IFDEF FPC_HAS_TYPE_DOUBLE}
  ...
{$ELSE}
{$IFDEF FPC_HAS_TYPE_SINGLE}
  ...
{$ELSE}
   {$FATAL Type Real should be defined as Single or as Double}
{$ENDIF} // FPC_HAS_TYPE_SINGLE
{$ENDIF} // FPC_HAS_TYPE_DOUBLE

This works. But is it a reliable way of doing? Since the
FPC_HAS_TYPE_XXX directives are not documented, I have a
little doubt ;-)
Thanks.
