# Note:

#

# This test checks the "direct linking to a dll" functionality.

#

# The test has 7 stages:

#

# 1. compile and link a test dll with ".dll" extension.

#

# 2. compile and link a test dll with ".sl" (i.e. != ".dll") extension.

#

# 3. compile and link a client application linking directly to the ".dll" dll built in 1.

#    This should produce no errors.

#

# 4. compile and link a client application linking directly to the ".sl" dll built in 2.

#    This should produce no errors.

#

# 5. compile and link a client application linking directly to a symlink into

#    the ".dll" dll built in 1.

#    This should produce no errors.

#

# 6. compile and link a client application linking directly to a symlink into

#    the ".sl" dll built in 1.

#    This should produce no errors.

#

# 7. run the produced executables

# This test can only be run on PE/COFF platforms.
