# MSVC-only: bump the default 1 MB Windows stack to 8 MB. clap-derive builds
# a large Command enum in this CLI (one variant per subcommand, each carrying
# flag args); in debug builds the enum is materialized on the stack without
# optimization and overflows the default Windows main-thread stack before
# even reaching our code.
#
# The /STACK: link-arg goes into the PE header's IMAGE_OPTIONAL_HEADER.
# SizeOfStackReserve at link time and applies to both debug and release
# builds — release artifacts ship with the same 8 MB stack reservation. At
# runtime the optimizer elides the enum from the stack frame, so release
# builds would not overflow without this setting; it is kept on for them so
# both build flavours produce binaries with identical stack metadata.
#
# `/STACK:` is an MSVC-linker (`link.exe` / `lld-link`) directive. The
# `target_env = "msvc"` selector below scopes the rustflag to the MSVC
# toolchain so `x86_64-pc-windows-gnu` (mingw) builds, which route link
# args through the GNU linker and reject `/STACK:`, are unaffected.
