# The C/C++/Fortran toolchain is not MSYS2's, but GCCToolchain_jll (Yggdrasil's
# `G/GCCToolchain`): GCC 15.2 built exactly like the GCC that CompilerSupportLibraries_jll
# comes from, whose runtime DLLs Julia ships (with SJLJ exceptions on i686). Installed in
# `G/GCCToolchain`): GCC 15.2 built like the GCC that CompilerSupportLibraries_jll comes
# from, whose runtime DLLs Julia ships (with SJLJ exceptions on i686). Installed in
# its own prefix, C:\gcc, ahead of MSYS2's in PATH; MSYS2's own programs keep loading the
# DLLs next to them.
# Like MSYS2's GCC, it uses unaligned vector moves by default, as 64-bit Windows does
# not align AVX stack slots (GCC PR 54412).
# Bump only together with CompilerSupportLibraries_jll's GCC.
