Build error with potential solution "error: reference to 'Print' is ambiguous"

OS: Windows 10
IDE: Visual Studio Code with Platformio extension
Platform: Arduino MKR NB 1500 (Arm Cortex-M0 32-bit SAMD21)
Compiler: arm-none-eabi-gcc
Standard: C++11

When building a project with this configuration, an error emerges saying "error: reference to 'Print' is ambiguous". It seems that the forward declaration class Print; in tinycbor.h is causing problems when using Print in tinycbor.cpp. I played around a little and removing the forward declaration and therefore adding #include <Print.h> to tinycbor.h did the trick.

I cannot tell if this causes the code to break in other configruations. Therefore I did not initiate a merge request.

I am sorry, I made a mistake here. I was still using the fork of tinycbor by Soburi.

With this version it also does not compile, but for a very different reason:

#error "Cannot implement open_memstream!"
