# Performed in the semantics tests.
|

# - AC_CONFIG
|

# They fail when the source does not exist.

|

# AC_INIT includes all the AC_INIT macros. Note that there is an

# - AC_PATH_PROGS?, AC_F77_FUNC

# They produce `= val' because $1, the variable used to store the result,

# Used in many places.

|

# Internal macros are used elsewhere.
|
|
# - AC_OUTPUT
|

# Already tested by `AT_CHECK_MACRO'.

# Is a number.

|
# - AC_PROG_CC, AC_C_(CONST|INLINE|VOLATILE), AC_PATH_XTRA
