patch 9.1.0622: MS-Windows: mingw-build can be optimized
Problem: MS-Windows: mingw-build can be optimized
Solution: use --gc-sections to reduce the size of the executable
(Ken Takata)
Use the --gc-sections linker option and the -ffunction-sections compiler
option to reduce the size of the executable files. To make these work,
the -fno-asynchronous-unwind-tables compiler option is also needed.
This is enabled by default and can be disabled by `USE_GC_SECTIONS=no`.
Note: A similar feature has been already used in MSVC. (The /OPT linker
option.)
