|
|
# Check how to enable compilation warnings. If LANGUAGE is not provided,

# then `C' is assumed (other options include `C++'). If CACHE-VAR is not
|
|
# provided, then it defaults to the name
|

|
|
# warnings (such as `-Wall') is discovered, then it is assigned to

# CACHE-VAR and ACTION-IF-FOUND is invoked; otherwise the empty string is

|
# assigned to CACHE-VAR and ACTION-IF-NOT-FOUND is invoked.
|
|
#
|
|
# IMPLEMENTATION NOTES
|
|
#
|
|
# On some platforms, it is more appropriate to use -Wmost rather than
|
|
# -Wall even if the compiler understands both, thus we attempt -Wmost
|
|
# before -Wall.
