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.
