When many #define statements are used, the following error is output during compilation.
eel750.h 349 cafe850 fatal error: F2120: compiler limit: preprocessor token buffer overflow  Total error(s) : 1 Total warning(s) : 0
I guess this error occurs because the preprocessor buffer of the C compiler overflows as a result of using too many preprocessors. Is this right?
To solve this problem, try increasing the limit number by using the -Xm option, which increases the maximum number of macro definitions (when -Xm is not specified, num is assumed to be 2047, and when ?Xm is specified, a value of up to 32767 can be specified).
