Compilation Issues with STM32 HAL Libraries in Strict ANSI-C Mode

@Sterling The errors you’re encountering suggest that there are features in the STM32 HAL code that are not compatible with C89. For instance, the inline keyword is not part of C89 but was introduced in C99. The STM32 HAL documentation may use "Strict ANSI-C" loosely, possibly meaning they aim for high portability rather than strict adherence to C89. you can use C99 standard, Instead of -std=c89, try using -std=c99. The inline keyword and other features would then be recognized.

CFLAGS = -std=c99\
         -pedantic-errors

CFLAGS = -std=c99\
         -pedantic-errors

If you must use C89, you may need to manually adjust the HAL code or find alternative ways to handle inline and other incompatible constructs. This can be very labor-intensive.
