AM_CONFIG_HEADER
AM_CYGWIN32
configure
is being run in the
`Cygwin32' environment. (FIXME xref). If so, define output
variable EXEEXT
to `.exe'; otherwise define it to the empty
string. Automake recognizes this macro and uses it to generate
`Makefile.in's which will automatically work under `Cygwin32'.
In the `Cygwin32' environment, gcc
generates executables
whose names end in `.exe', even if this was not specified on the
command line. Automake adds special code to `Makefile.in' to
gracefully deal with this.
AM_FUNC_STRTOD
strtod
function is not available, or does not work
correctly (like the one on SunOS 5.4), add `strtod.o' to output
variable LIBOBJS
.
AM_FUNC_ERROR_AT_LINE
error_at_line
is not found, then add
`error.o' to LIBOBJS
.
AM_FUNC_MKTIME
mktime
function. If not found, add
`mktime.o' to `LIBOBJS'.
AM_FUNC_OBSTACK
AM_C_PROTOTYPES
AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL
TIOCGWINSZ
requires `<sys/ioctl.h>', then
define GWINSZ_IN_SYS_IOCTL
. Otherwise TIOCGWINSZ
can be
found in `<termios.h>'.
AM_INIT_AUTOMAKE
AC_DEFINE
's `PACKAGE' and `VERSION'. This
can be avoided by passing in a non-empty third argument.
AM_PATH_LISPDIR
emacs
, and, if found, sets the output
variable lispdir
to the full path to Emacs' site-lisp directory.
AM_PROG_CC_STDC
CC
to make it so. This macro tries various
options that select ANSI C on some system or another. It considers the
compiler to be in ANSI C mode if it handles function prototypes correctly.
If you use this macro, you should check after calling it whether the C
compiler has been set to accept ANSI C; if not, the shell variable
am_cv_prog_cc_stdc
is set to `no'. If you wrote your source
code in ANSI C, you can make an un-ANSIfied copy of it by using the
ansi2knr
option.
AM_PROG_INSTALL
AC_PROG_INSTALL
, but also defines INSTALL_SCRIPT
.
AM_PROG_LEX
AC_PROG_LEX
with AC_DECL_YYTEXT
, but uses the
missing
script on systems that do not have lex. `HP-UX 10'
is one such system.
AM_SANITY_CHECK
AM_INIT_AUTOMAKE
.
AM_SYS_POSIX_TERMIOS
am_cv_sys_posix_termios
to
`yes'. If not, set the variable to `no'.
AM_TYPE_PTRDIFF_T
AM_WITH_DMALLOC
dmalloc
package. If the user configures with
`--with-dmalloc', then define WITH_DMALLOC
and add
`-ldmalloc' to LIBS
. The dmalloc
package can be
found at ftp://ftp.letters.com/src/dmalloc/dmalloc.tar.gz
AM_WITH_REGEX
configure
command line. If
specified (the default), then the `regex' regular expression
library is used, `regex.o' is put into `LIBOBJS', and
`WITH_REGEX' is defined.. If `--without-regex' is given, then
the `rx' regular expression library is used, and `rx.o' is put
into `LIBOBJS'.
