does not give a valid preprocessing token/Since 1.8.6

[Keugon]

PreWord iam not a Programmer just using Marlin for my 3d Printer
This Issue only appears when I try to compile it with 1.8.6 by 1.8.4 everything is fine i hope someone can identify the "Real Bug" here

I previously thought this was arduino/arduino-preprocessor#6 but now I understand that Arduino IDE 1.8.6 doesn't actually use arduino-preprocessor (despite bundling that tool). The MCVE in arduino/arduino-preprocessor#6 doesn't result in an error in Arduino IDE 1.8.6. When I replace Arduino IDE 1.8.6's arduino-builder 1.4.0 with the previous arduino-builder 1.3.25 release the bug reported here does not occur. So this is an arduino-builder bug rather than an arduino-preprocessor bug.

[facchinm]

I started bisecting this issue (it was tough since it falls into the compiler cache optimizations, so I was getting a lot of false positives). Anyway, the commit that introduced the regression is arduino/arduino-builder@fcc9c5d

@matthijskooijman do you have any spare time to take a look? Reverting just works in getting rid of the expansion bug but I'd like to understand clearly what is going on

[Keugon]

Huh not epected that reaction on that just wana say thank you for care about my porly sumited issue
