Why Doesn't My MinGW g Compiler Recognize `to_string()`?

String Conversion Pitfalls with MinGW g

In your attempt to utilize the to_string() function to convert a long integer to a string for storage purposes, you encountered an unexpected error "to_string' is not a member of 'std'" while compiling with g under MinGW. This error stems from a known bug specific to MinGW.

The to_string() function was introduced in the C 11 standard. While g with the -std=c 0x flag enables C 11 features, there's a limitation in Mingw's implementation. The to_string() function is supported in later versions of MinGW (beyond GCC 4.8.0) or by using alternative toolchains like MinGW-w64 or Nuwen MinGW.

To resolve this issue, you can adopt one of the following solutions:

1. Upgrade to Newer MinGW Version: If possible, upgrade your MinGW installation to a version where the to_string() function is supported (post-4.8.0).
2. Apply Patch: There's a patch available to address this bug in older versions of MinGW. You can obtain it from the linked Bugzilla page in the problem description.
3. Switch to Alternative Toolchain: Consider using alternative toolchains such as MinGW-w64 or Nuwen MinGW, which provide support for the to_string() function.
