cat <<_ACEOF `configure' configures this package to adapt to
many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify
them as VAR=VALUE. See below for descriptions of some of the
useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this pack-
age
--help=recursive display the short help of all the in-
cluded packages
-V, --version display version information and exit
-q, --quiet, --silent do not print `checking...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for `--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir
or `..']
Installation directories:
--prefix=PREFIX install architecture-independent files
in PREFIX [$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in
EPREFIX [PREFIX]
By default, `make install' will install all the files in `$ac_de-
fault_prefix/bin', `$ac_default_prefix/lib' etc. You can specify
an installation prefix other than `$ac_default_prefix' using
`--prefix', for instance `--prefix=OME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PRE-
FIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data
[PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PRE-
FIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR] _ACEOF
cat <<_ACEOF
Program names:
--program-prefix=PREFIX prepend PREFIX to installed
program names
--program-suffix=SUFFIX append SUFFIX to installed
program names
--program-transform-name=PROGRAM run sed PROGRAM on installed
program names _ACEOF fi
if test -n "$ac_init_help"; then
cat <<_ACEOF
Optional Features:
--disable-FEATURE do not include FEATURE (same as --en-
able-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-dmalloc use the dmalloc heap debug library
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have li-
braries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<in-
clude dir> if
you have headers in a nonstandard directory <in-
clude dir>
CPP C preprocessor
Use these variables to override the choices made by `configure'
or to help it to find libraries and programs with nonstandard
names/locations.

# configure is writing to config.log, and then calls config.sta-
tus. # config.status does its own redirection, appending to con-
fig.log. # Unfortunately, on DOS this fails, as config.log is
still kept open # by configure, so config.status won't be able to
write to it; its # output is simply discarded. So we exec the FD
to /dev/null, # effectively closing config.log, so it can be
properly (re)opened and # appended to by config.status. When
coming back to configure, we # need to make the FD available
again. if test "$no_create" != yes; then
