|
# DESCRIPTION
|
|
|
|
|
#
|
|
|
|
|
# Check whether the given linker FLAGS work with the current language's
|
|
|
|
|
# linker, or whether they give an error.
|
|
|
|
|
#
|
|
|
|
|
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
|
|
|
|
|
# success/failure.
|
|
|
|
|
#
|
|
|
|
|
# PROGRAM-SOURCE is the program source to link with, if needed
|
|
|
|
|
#
|
|
|
|
|
# NOTE: Based on AX_CHECK_COMPILER_FLAGS.
