# build.ps1 — 编译 Deshab PE 系统工具（mingw-w64 g++）
#
# GUI 工具 → SYSTEM/program/*.exe（开始菜单 STARTMENU.CNF 启动，窗口嵌入桌面）
# CLI 工具 → SYSTEM/bin/*.exe（CMD 里敲名字运行，输出走串口）
#
# 编译模式与 CODE/tools/pe-samples/hello64.c 相同：
#   -nostartfiles -Wl,--entry,main -Wl,--image-base,0x140000000
# （无 CRT 启动；只准调 pe_shim 表内的 Win32 面）
#
# 用法: powershell -File build.ps1 [-Gxx <g++路径>]
