# 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.
