C++ mutex in namespace std does not name a type

Question

I\'m writing a simple C++ program to demonstrate the use of locks. I am using codeblocks and gnu gcc compiler.

I encountered this same problem when using MingW-W64 7.2.0. I tested out several different Windows builds from the mingw-64 download page, and found that MinGW-W64 GCC-8.1.0 supports mutex and contains the pthread library. When installing, I selected the following options:

• x86_64
• posix
• seh

My multi-threaded code based on pthreads now compiles and runs cleanly on both Windows and Linux with no changes.

This version is leaner than the 7.3.0 build I was using because it doesn't have a CygWin environment or package manager. I also copied mingw32-make.exe to make.exe so my Makefile wouldn't need to be modified. The installer creates a "Run terminal" link in the Windows Start Menu.
