Kamil Dudka 4e7690ebec configure: use well-known file name conftest.c 
... for configuration checks.  Compiler wrappers check for this name
in order to skip any instrumentation of the build that is intended
for regular source files only.

\`configure' configures this package to adapt to many kinds of systems.
Usage: ./configure [OPTION]...
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, \`make install' will install all the files in
\`/usr/local/bin', \`/usr/local/lib' etc. You can specify
an installation prefix other than \`/usr/local' using \`--prefix',
for instance \`--prefix=$HOME'.
For better control, use the options below.
--disable-readline Disable line editing support
--without-editline Don't use editline even if it is available
--disable-sechash Disable support for hashes other than MD5
--without-nettle Don't use nettle even if it is available
--without-nss Don't use NSS even if it is available
--without-tomcrypt Don't use libtomcrypt even if it is available
--disable-nts Disable NTS support
--without-gnutls Don't use gnutls even if it is available
--disable-cmdmon Disable command and monitoring support
--disable-ntp Disable NTP support
--disable-refclock Disable reference clock support
--disable-phc Disable PHC refclock driver
--disable-pps Disable PPS refclock driver
--disable-ipv6 Disable IPv6 support
--disable-rtc Don't include RTC even on Linux
--disable-privdrop Disable support for dropping root privileges
--without-libcap Don't use libcap even if it is available
--enable-scfilter Enable support for system call filtering
--without-seccomp Don't use seccomp even if it is available
--disable-asyncdns Disable asynchronous name resolving
--disable-forcednsretry Don't retry on permanent DNS error
--without-clock-gettime Don't use clock_gettime() even if it is available
--disable-timestamping Disable support for SW/HW timestamping
--enable-ntp-signd Enable support for MS-SNTP authentication in Samba
--with-ntp-era=SECONDS Specify earliest assumed NTP time in seconds
since 1970-01-01 [50*365 days ago]
--with-user=USER Specify default chronyd user [root]
--with-hwclockfile=PATH Specify default path to hwclock(8) adjtime file
--with-pidfile=PATH Specify default pidfile [/var/run/chrony/chronyd.pid]
--with-rtcdevice=PATH Specify default path to RTC device [/dev/rtc]
--with-sendmail=PATH Path to sendmail binary [/usr/lib/sendmail]
--enable-debug Enable debugging support
Fine tuning of the installation directories:
--sysconfdir=DIR chrony.conf location [/etc]
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--datarootdir=DIR data root [PREFIX/share]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/chrony]
--localstatedir=DIR modifiable single-machine data [/var]
--chronyrundir=DIR location for chrony sockets [LOCALSTATEDIR/run/chrony]
--chronyvardir=DIR location for chrony data [LOCALSTATEDIR/lib/chrony]
Overriding system detection when cross-compiling:
--host-system=OS Specify system name (uname -s)
--host-release=REL Specify system release (uname -r)
--host-machine=CPU Specify machine (uname -m)
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
CPPFLAGS C preprocessor flags, e.g. -I<include dir> if you have
headers in a nonstandard directory <include dir>
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
PKG_CONFIG path to pkg-config utility
PKG_CONFIG_PATH
directories to add to pkg-config's search path
PKG_CONFIG_LIBDIR
path overriding pkg-config's built-in search path
Use these variables to override the choices made by \`configure' or to help
it to find libraries and programs with nonstandard names/locations.
