# Tests should be able to handle paths with spaces.
#
# One of the things ./validate (without --fast) does is check if binary
# distributions can succesfully be installed and used in paths containing
# spaces.
#
# It does so in the following way:
# * create a binary distribution in 'bindistprep/'.
# * install that binary distribution in 'bindisttest/install dir/'
# * run the testsuite with BINDIST=YES
#
# BINDIST=YES tells the testsuite driver to use
# 'bindisttest/install dir/bin/ghc' instead of 'inplace/bin/ghc-stage2' as
# TEST_HC.
#
# Before, if a GHC developer forgot to quote TEST_HC in their Makefile when
# adding a new test, the test would fail with a puzzling "command not found:
# bindisttest/install" error (but only when validating).
#
# Therefore, we now:
# * make sure 'bindisttest/install' does exist, and show a nice message when
# it is executed.
# * let the default value of TEST_HC also contain spaces
# (i.e. 'inplace/test spaces/ghc-stage2'), such that the test always
# fails, also without BINDIST=YES, and again show a nice message when it
# indeed does so, through 'inplace/test'.
# The `wildcard` function requires spaces to be escaped. Other gnu make
# functions can't seem to handle spaces at all (e.g. `abspath`).
