+# Enable static linking for C runtime library on Windows.
+#
+# Rust uses the msvc toolchain on Windows,
+# which by default dynamically links the C runtime (CRT) to the binary.
+#
+# This creates a runtime dependency on the Visual C++ Redistributable (`vcredist`),
+# meaning the target machine must have `vcredist` installed for the application to run.
+#
+# Since `portable` version doesn't have an installer,
+# we can't rely on it to install dependencies, so this config.
+#
+# Basically:
+# - The `+crt-static` flag instructs the Rust compiler to statically link the C runtime for Windows builds.\
+# - To avoids runtime errors related to missing `vcredist` installations.
+# - Results in a larger binary size because the runtime is bundled directly into the executable.
+#
+# For MSVC targets specifically, it will compile code with `/MT` or static linkage.
