  25 # Note:
  26 #
  27 # This test checks the "direct linking to a dll" functionality.
  28 #
  29 # The test has 7 stages:
  30 #
  31 # 1. compile and link a test dll with ".dll" extension.
  32 #
  33 # 2. compile and link a test dll with ".sl" (i.e. != ".dll") extension.
  34 #
  35 # 3. compile and link a client application linking directly to the ".dll" dll built in 1.
  36 #    This should produce no errors.
  37 #
  38 # 4. compile and link a client application linking directly to the ".sl" dll built in 2.
  39 #    This should produce no errors.
  40 #
  41 # 5. compile and link a client application linking directly to a symlink into
  42 #    the ".dll" dll built in 1.
  43 #    This should produce no errors.
  44 #
  45 # 6. compile and link a client application linking directly to a symlink into
  46 #    the ".sl" dll built in 1.
  47 #    This should produce no errors.
  48 #
  49 # 7. run the produced executables
  50
  51 # This test can only be run on PE/COFF platforms.
