27# Note:

29# This test checks the "direct linking to a dll" functionality with stdcall
30# and fastcall fixup.
31#
32# The test has 7 stages:
33#
34# 1. compile and link a test dll with ".dll" extension.
35#
36# 2. compile and link a test dll with ".sl" (i.e. != ".dll") extension.
37#
38# 3. compile and link a client application linking directly to the ".dll" dll built in 1.
39#    This should produce no errors.
40#
41# 4. compile and link a client application linking directly to the ".sl" dll built in 2.
42#    This should produce no errors.
43#
44# 5. compile and link a client application linking directly to a symlink into
45#    the ".dll" dll built in 1.
46#    This should produce no errors.
47#
48# 6. compile and link a client application linking directly to a symlink into
49#    the ".sl" dll built in 1.
50#    This should produce no errors.
51#
52# 7. run the produced executables
53
54# This test can only be run on PE/COFF platforms.
