#
# This is the second obstacle in this package, and the first one hid it: before
# autoconf-archive existed, configure died on
#
#   configure.ac:139: error: undefined or overquoted macro: AC_MSG_WARN
#
# which named a macro that exists. An AX_* macro was missing, m4 quoting came
# apart, and autoconf blamed the next thing it recognised. With the archive
# installed, configure gets far enough to ask for cmocka.
#
# cmocka is a C unit-test framework, wanted only to build tests that this
# bootstrap does not run -- makepkg is invoked with --nocheck for the whole first
# pass. --disable-unit is tpm2-tss's own switch; the PKGBUILD passes --enable-unit
# in its options array.
