Description:
------------
The form of an extended module is created by ext_skel.
(_ is contained in that case.)
ex. ext_skel --extname=aaa_bbb_ccc

// config.m4 generated
PHP_ARG_ENABLE(aaa_bbb_ccc, whether to enable aaa_bbb_ccc support,
[  --enable-aaa_bbb_ccc           Enable aaa_bbb_ccc support])
if test "$PHP_AAA_BBB_CCC" != "no"; then
  PHP_NEW_EXTENSION(aaa_bbb_ccc, aaa_bbb_ccc.c, $ext_shared)
fi

I want to take in on a PHP itself.(It isn't extension module, such as .so and .dll.)
I did autoconf by the root directory.

// configure generated
...
echo "$as_me:$LINENO: checking whether to enable aaa_bbb_ccc support" >&5
echo $ECHO_N "checking whether to enable aaa_bbb_ccc support... $ECHO_C" >&6
# Check whether --enable-aaa_bbb_ccc or --disable-aaa_bbb_ccc was given.
if test "${enable_aaa_bbb_ccc+set}" = set; then
  enableval="$enable_aaa_bbb_ccc"
  PHP_AAABBBCCC=$enableval
else

  PHP_AAABBBCCC=no
...

Although we expected that PHP_AAA_BBB_CCC was outputted, we are outputted with PHP_AAABBBCCC.
It will be linked even if it doesn't specify an option( --enable-aaa_bbb_ccc ) to be configure.

It was avoidable when performing it as follows.
