# BuildSharedSnapshot.sh — Build Denemo Windows package with bundled LilyPond
# ==============================================================================
# LILYPOND STRATEGY:
#   LilyPond lives in denemo/lilypond/ as a self-contained subdirectory.
#   Its DLLs are NOT merged into denemo/bin/ — doing so overwrites the GLib
#   DLLs Denemo was compiled against by MXE, causing the libglib crash.
#   Kept isolated, LilyPond uses its own DLLs and Denemo uses its own.
#   Configure Denemo to invoke:  lilypond\bin\lilypond.exe  (relative path)
#
# SIZE STRATEGY:
#   MXE pulls in many transitive deps (video codecs, ICU, crypto, terminfo…)
#   that Denemo never uses at runtime.  The cleanup section removes ~200 MB.
#   Items marked "MAYBE NEEDED" are uncertain — if Denemo breaks, restore them.

# 13. Fix Guile .go file timestamps
#
# PROBLEM: When Windows unzips, it sets ALL file timestamps to "right now".
#   This makes .scm source files appear NEWER than their .go compiled cache.
#   Guile then tries to recompile the .go files at runtime, which fails with:
#   "Wrong number of arguments to #<boot-closure>" — the crash you saw.
#
# FIX: Stamp every .go file to a far-future date (2038). Guile only checks
#   whether .go is newer than .scm — it doesn't care how far in the future
#   the .go is. This is safe, simple, and survives any unzip timestamp reset.
