📋 问题概述

line 306 处将 ex_wundo 和 ex_rundo 声明为 static，但 line 8464 和 8474 处的函数定义缺少 static 关键字。C 语言标准规定，若函数先被声明为静态链接，后续定义也必须为静态，否则构成约束违规（constraint violation），将直接导致编译失败。

📍 问题详情

🟡 问题 1 | 严重程度: MEDIUM | 行号: 1-10

💬 详细说明：

  • line 1 处将 ex_wundo 和 ex_rundo 声明为 static，但 line 8464 和 8474 处的函数定义缺少 static 关键字。C 语言标准规定，若函数先被声明为静态链接，后续定义也必须为静态，否则构成约束违规（constraint violation），将直接导致编译失败。

📝 问题代码：

void

💡 修复建议：

在 line 1 和 1 的函数定义前添加 static 关键字，使其与 line 306-307 的声明保持一致。这符合 Vim 中命令处理函数通常为内部静态函数的惯例。

✅ 修复示例：

    #ifdef FEAT_PERSISTENT_UNDO
    static void
ex_wundo(eap)
    exarg_T *eap;
{
    char_u hash[UNDO_HASH_SIZE];

    u_compute_hash(hash);
    u_write_undo(eap->arg, eap->forceit, curbuf, hash);
}
