# Template file for 'libgccjit'
# Revbump libtool when updating gcc, since it hardcodes some internal compiler paths

# we are using a 10-stable git snapshot alpine is using in order
# to get regression fixes not yet incorporate into a stable release
# it should be possible to switch back to stable with 10.3 or 11
