[MinGW] Link pthread statically [Ubuntu]

※MinGWアプリがlibwinpthread-1.dllを要求するのを(-staticせずに)防ぐには以下のスクリプトを実行します。※

In the latest, the very basic programs not-using threads are also linked to pthread. The worse is the library is libpthread.dll.a in default, which requires libwinpthread-1.dll runtime.

Therefore, linking pthread statically is preferred. You can use -static of course, but I still wanted to use msvcrt.dll as C runtime.

I use the Ubuntu package of MinGW. So, to prevent dynamic library, I have done the following:

#!/bin/bash
for dir in i686-w64-mingw32 x86_64-w64-mingw32; do 
mv /usr/${dir}/lib/libpthread.dll.a{,_}
mv /usr/${dir}/lib/libwinpthread.dll.a{,_}
mv /usr/${dir}/lib/libwinpthread-1.dll{,_}
done
