The gcc_s part of the filename indicates that the DLL is a shared support library for GCC. The seh in the filename stands for "Structured Exception Handling," which is a method for handling exceptions (unexpected or exceptional conditions) in Windows. The -1 typically signifies the version or variant of the DLL.
