IntelliSense: invalid macro definition: ARDUINO_AVR_ATTINY45-8

It looks like it might be the "-" in the macro definition. AVR Definitions that don't have a - seem to be working fine, but I'm having the same problem with 

"ARDUINO_AVR_ATTINY45-8"

If I edit the project file and change the preprocessor definitions, and change that one to:

"ARDUINO_AVR_ATTINY45_8"

Intellisense and error checking start working fine again. Was this issue ever addressed?

I'm fairly certain there's plenty of code that depends on the appropriate definition of ARDUINO_AVR_ATTINY45-8, I just changed it briefly to test if that was the problem.

A quick work-around is to pick a board type without a - in it until you need to compiled and then compile.. but that can be sketchy if you're burning directly to boards without a bootloader.

I looked a bit further and found that two things are happening, "-" is used in the command line to specify the options such as the preprocessor definitions, so I was checking to see if there was a way to escape that character, but this link:

https://msdn.microsoft.com/en-us/library/teas0593.aspx

specifies the appropriate use of the #define directive for Visual C++, and it says it should be:

#define identifier token-string(opt)

According to this page:

https://msdn.microsoft.com/en-us/library/565w213d.aspx

a dash is not allowed as part of an identifier. So it would seem the problem is with that particular definition. Is that provided by atmel, or by Visual Micro?

Hi,

Last year Arduino started using this type of define but it isn't relevant for all boards.

The ATTINY boards doesn't need it we will remove it in the next service pack due in a week or so

Thanks
