\`configure' configures R 1.5.0 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 package
      --help=recursive    display the short help of all the included 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

  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

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]
  --datadir=DIR          read-only architecture-independent data [PREFIX/share]
  --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR   modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
  --libdir=DIR           object code libraries [EPREFIX/lib]
  --includedir=DIR       C header files [PREFIX/include]
  --oldincludedir=DIR    C header files for non-gcc [/usr/include]

  --program-suffix=SUFFIX            append SUFFIX to installed program names

X features:
  --x-includes=DIR    X include files are in DIR
  --x-libraries=DIR   X library files are in DIR

System types:
  --build=BUILD     configure for building on BUILD [guessed]

### DLL stuff.

## We need to determine the following:
##
## MAIN_LD, MAINLD_FLAGS
##   command and flags for loading the main binary so that it will load
##   shared libraries (DLLs) at runtime, also for profiling.
## CPICFLAGS, CXXPICFLAGS, FPICFLAGS
##   flags for compiling C, C++, and Fortran library code
## SHLIB_LD, SHLIB_LDFLAGS
##   command and flags for creating DLLs (which contain object files
##   from a C or Fortran compiler).
## SHLIB_CXXLD, SHLIB_CXXLDFLAGS
##   command and flags for creating DLLs which contain object files from
##   a C++ compiler.  According to autoconf, the C++ compiler/linker
##   must be used for linking in this case (since special C++-ish things
##   need to happen at link time like calling global constructors,
##   instantiating templates, enabling exception support, etc.).
##
## The procedure is as follows.
##
## * We use applicable values from imake in case its CC is ours.
## * Irrespective of that, we think we know what to do with GNU tools
##   (GNU C, Fortran, and C++ compilers).
## * Then, use platform specific overrides.
## * As a final safeguard, values from the environment (as specified in
##   one of the configuration files or at the configure command line)
##   override anything we figure out in the case of compiler flags; for
##   linker flags (*LDFLAGS), environment settings override our results
##   if the corresponding *LD variable was set, and add otherwise.
##
## NOTE: We do not provide defaults for the *LDFLAGS, taking a defensive
## approach.  In case we cannot figure out {MAIN,SHLIB}_LDFLAGS and the
## user did not provide defaults, an error results.  A warning is given
## if nothing was obtained for SHLIB_CXXLDFLAGS.
##
## Note also that some systems (notably AIX) do not allow for unresolved
## symbols at link time.  For such systems, we link against -lm (in case
## it exists) when building a shlib module via SHLIB_LIBADD.
