LittleFS declaration conflict error for ESP32S3

[perigalacticon]

Arduino IDE version: 1.8.19 (latest).
ESP Boards version: 3.0.5 (latest).
Board selection: ESP32S3_Dev_Module.
Board Partition Scheme: Default 4MB with spiffs (1.2MB APP / 1.5MB SPIFFS).
Example ino file: ESP32_SDcard_jpeg

When I compile this for ESP32S3 Dev Module I get this error:

I can't quite figure it out, I am not a professional programmer, but I'd really like to use your libraries. Can you find the solution for this?

I forgot I had moved the location of the JPEGDecoder.h include statement to the top of the includes list to see if it would clear up a different error I got previously. Putting JPEGDecoder.h at the bottom of the includes list and this stopped the LittleFS library error, but now I get the error I had first: "invalid conversion from 'uint32_t ()(JDEC, uint8_t*, uint32_t)' {aka 'long unsigned int ()(JDEC, unsigned char*, long unsigned int)'} to 'UINT ()(JDEC, BYTE*, UINT)' {aka 'unsigned int ()(JDEC, unsigned char*, unsigned int)'} [-fpermissive]":

2nd EDIT: I also forgot to mention that the problem I am having is when I try to also include the TFT_eFEX library. I see TFT_eFX.h includes JPEGDecoder.h, so If I comment out the include of the JPEGDecoder library on my sketch I still get the same error below:

Error compiling for board ESP32S3 Dev Module.

Something is trying to convert from a 32bit var to an 8bit var.

I'm also having compilation errors related to this library and multiple defines of SPIFFS and LittleFS. I haven't tried moving the library include around but I'm trying to get ESP32 Marauder software to compile and it won't because of this library. I could mod the library but I feel there's something else going on here. I'm trying to compile for the T-display S3 pro.

If anyone is still interested, I have created a minimal PR to fix this
PR90
I'm not sure if it's the best way to fix this, history of related changes and their logic are not entirely clear to me.
But it works, and looks logical.
