Compiler warnings

[vkichline]

Using build e41325a from 11/5, I get the following non-fatal warning when compiling in PlatformIO, standard compiler settings.
M5Core2 is current, not 0.0.1:

C:/users/van/.platformio/lib/Core2ez/src/ezSound.h:13:0: warning: "TWO_PI" redefined

C:/users/van/.platformio/lib/Core2ez/src/ezTheme.h:12:8: warning: extra tokens at end of #endif directive [-Wendif-labels]

I get this one a lot, and I think it's an annoyance only. Seems like %ld takes care of it though:

C:\users\van\.platformio\lib\Core2ez\src\ezDisplayZone.cpp:28:48: warning: format '%d' expects argument of type 'int', but argument 3 has type 'long int' [-Wformat=]
     Serial.printf("tmpspr = %d\n", (long)tmpspr);
