26# Note:

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