Subject: fix-gnulib: Fix order-only hack with HP-UX make.
X-Git-Url: https://git.draconx.ca/gitweb/dxcommon.git/commitdiff_plain/e218d4445fa5a2015163cf50d847980ff3240b36?ds=sidebyside;hp=e218d4445fa5a2015163cf50d847980ff3240b36

fix-gnulib: Fix order-only hack with HP-UX make.

HP-UX make gets confused by the space in $(findstring ...,$(...))
syntax: instead of expanding to the empty string as desired, it
mismatches the parentheses and we are left with a single ).  E.g.:

  % cat >Makefile <<'EOF'
  all:
	@echo '$(a $(b))'
EOF
  % make
  )

Since $(x) and ${x} are equivalent in Make, a neat solution is to
just replace one set of parentheses with braces; now there are no
nested parentheses to mismatch in the first place.
