# link.sh -- try linking Vim with different sets of libraries, finding the
# minimal set for fastest startup. The problem is that configure adds a few
# libraries when they exist, but this doesn't mean they are needed for Vim.
#
# Warning: This fail fail miserably if the linker doesn't return an error
# code!
#
# Otherwise this script is fail-safe, falling back to the original full link
# command if anything fails.
