AC_CONFIG_HEADERS(config.h) Now I want to be sure that if a source file does not include config.h , compile fails. My current solution is to redefine int on command line and fix it back in config.h :
#include #define uchar unsigned char sbit ST = P2 ^ 7; sbit EOC = P3 ^ 4; sbit OE = P2 ^ 我来答 可选中1个或多个下面的关键词，搜索相关资料。
这是一个 C/C++ 语言中的预处理指令，用于定义一个新的标识符 "uchar"，表示"无符号字符型"。同时，这个标识符被定义成了一个宏，它会在编译时被替换成 "unsigned char"，这样在程序中就可以直接使用 "uchar" 来表示无符号字符型数据。
