When default headers are used, check for their presence.
Suggested by Jim. * acgeneral.m4 (_AC_INIT_DEFAULTS): Don't define ac_includes_default, since... (_AC_INCLUDES_DEFAULT_REQUIREMENTS): this new macro does. (AC_INCLUDES_DEFAULT): Require the former when default includes are used. (AC_CHECK_MEMBERS, _AC_CHECK_TYPE_NEW): Don't require AC_HEADERS_STDC, that's a job for stupendous AC_INCLUDES_DEFAULT. * acfunctions.m4 (AC_FUNC_MALLOC): Check for stdlib.h.

# The end-of-line after `$[1]' below is meant, and it is actually
|
||||
# because this new line is meant that we don't use m4_default. The
|
||||
# problem is that this macro is used *unquoted* in AC_TRY_COMPILE
|
||||
# etc. It is used unquoted because unfortunately (this is a real
|
||||
# pain), AC_TRY_COMPILE is over quoting some of its arguments. This
|
||||
# is a sad decision.
|
||||
#
|
||||
# Still, there are calls such as this
|
||||
#
|
||||
# AC_TRY_COMPILE(AC_INCLUDES_DEFAULT([#include <pwd.h>]),
|
||||
# AC_BLAH_BLAH..)
|
||||
#
|
||||
# Because AC_INCLUDES_DEFAULT *has* to be unquoted, after evaluation,
|
||||
# if there were no end of line, you'd get
|
||||
#
|
||||
# AC_TRY_COMPILE(#include <pwd.h>,
|
||||
# AC_BLAH_BLAH,
|
||||
# AC_MORE_BLAH_BLAH)
|
||||
#
|
||||
# i.e. the first argument given to AC_TRY_COMPILE is
|
||||
#
|
||||
# #include <pwd.h>,
|
||||
# AC_BLAH_BLAH
|
||||
#
|
||||
# (note how the comma was swallowed because of the comment mark) and
|
||||
# the second is
|
||||
#
|
||||
# AC_MORE_BLAH_BLAH
|
||||
#
|
||||
# so all the arguments are shifted.
|

# problem is that this macro is used *unquoted* in AC_TRY_COMPILE

||||
# etc. It is used unquoted because unfortunately (this is a real
|
||||
# pain), AC_TRY_COMPILE is over quoting some of its arguments. This

# is a sad decision.

#
