  28 # This test checks the "direct linking to a dll" functionality.
  29 #
  30 # The test has 7 stages:
  31 #
  32 # 1. compile and link a test dll with ".dll" extension.
  33 #
  34 # 2. compile and link a test dll with ".sl" (i.e. != ".dll") extension.
  35 #
  36 # 3. compile and link a client application linking directly to the ".dll" dll built in 1.
  37 #    This should produce no errors.
  38 #
  39 # 4. compile and link a client application linking directly to the ".sl" dll built in 2.
  40 #    This should produce no errors.
  41 #
  42 # 5. compile and link a client application linking directly to a symlink into
  43 #    the ".dll" dll built in 1.
  44 #    This should produce no errors.
  45 #
  46 # 6. compile and link a client application linking directly to a symlink into
  47 #    the ".sl" dll built in 1.
  48 #    This should produce no errors.
  49 #
  50 # 7. run the produced executables
  51
  52 # This test can only be run on PE/COFF platforms.
