if not exist ../../lib/gcc_lib/mswud/wx mkdir ../../lib/gcc_lib/mswud/wx

process_begin: CreateProcess(NULL, -c "if not exist ../../lib/gcc_lib/mswud/wx mkdir ../../lib/gcc_lib/mswud/wx", ...) failed.

make (e=2)

产生错误的原因是因为安装了MSYS后，利用Make命令会首先执行MSYS中的SHELL命令，从而会导致编译错误，对于这种情况，可以修改 $(WX)/build/msw目录中的makefile.gcc文件，使其默认采用CMD命令行。
