// The following two macros are used to create unique variable names
// by the means of the __LINE__ builtin macro.
// The ## token paste operator must be called inside a macro and must
// precede a macro parameter. This is why we can't use directly
//
// #define UNIQUEVARIABLE int name ## __LINE__
//
// We need something like
//
// #define PASTE(x,y) x ## y
// #define UNIQUEVARIABLE int PASTE(x,__LINE__)
//
// But this doesn't work since the specification of the token pasting operator is
//
// "If a formal parameter in a macro definition is preceded or followed by the token-pasting operator,
// the formal parameter is immediately replaced by the __unexpanded__ actual argument. Macro expansion
// is __not performed__ on the argument prior to replacement."
//
// So to actually have __LINE__ expanded we need another level of indirection
