   1261 'configure' configures blc 0.1.0 to adapt to many kinds of systems.
   1262 
   1263 Usage: $0 [OPTION]... [VAR=VALUE]...
   1264 
   1265 To assign environment variables (e.g., CC, CFLAGS...), specify them as
   1266 VAR=VALUE.  See below for descriptions of some of the useful variables.
   1267 
   1268 Defaults for the options are specified in brackets.
   1269 
   1270 Configuration:
   1271   -h, --help              display this help and exit
   1272       --help=short        display options specific to this package
   1273       --help=recursive    display the short help of all the included packages
   1274   -V, --version           display version information and exit
   1275   -q, --quiet, --silent   do not print 'checking ...' messages
   1276       --cache-file=FILE   cache test results in FILE [disabled]
   1277   -C, --config-cache      alias for '--cache-file=config.cache'
   1278   -n, --no-create         do not create output files
   1279       --srcdir=DIR        find the sources in DIR [configure dir or '..']
   1280 
   1281 Installation directories:
   1282   --prefix=PREFIX         install architecture-independent files in PREFIX
   1283                           [$ac_default_prefix]
   1284   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
   1285                           [PREFIX]
   1286 
   1287 By default, 'make install' will install all the files in
   1288 '$ac_default_prefix/bin', '$ac_default_prefix/lib' etc.  You can specify
   1289 an installation prefix other than '$ac_default_prefix' using '--prefix',
   1290 for instance '--prefix=\$HOME'.
   1291 
   1292 For better control, use the options below.
   1293 
   1294 Fine tuning of the installation directories:
   1295   --bindir=DIR            user executables [EPREFIX/bin]

   1343 Some influential environment variables:
   1344   CXX         C++ compiler command
   1345   CXXFLAGS    C++ compiler flags
   1346   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
   1347               nonstandard directory <lib dir>
   1348   LIBS        libraries to pass to the linker, e.g. -l<library>
   1349   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
   1350               you have headers in a nonstandard directory <include dir>
   1351 
   1352 Use these variables to override the choices made by 'configure' or to help
   1353 it to find libraries and programs with nonstandard names/locations.

   2742 
   2743 Your 'rm' program seems unable to run without file operands specified
   2744 on the command line, even when the '-f' option is present.  This is contrary
   2745 to the behaviour of most rm programs out there, and not conforming with
   2746 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
   2747 
   2748 Please tell bug-automake@gnu.org about your system, including the value
   2749 of your $PATH and any error possibly output before this message.  This
   2750 can help us improve future automake versions.
