Compiler Warning when using U8g2 with MiniCore

[Multiinventor]

Hi,
compiling U8g2 with MiniCore (strict warnings enabled) throws a sign-compare warning in u8g2_arc.c at line 78:

\Arduino\libraries\U8g2\src\clib\u8g2_arc.c:78:16: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
else if (d < 2 * (rad - y))
^

If important:

I am using:

• Atmega328P
• SSD1306
• U8G2_SSD1306_128X64_NONAME_2_HW_I2C display(U8G2_R0, U8X8_PIN_NONE);

Which compiler do you use? Is it the Arduino IDE or something else?
