/* build
A C++ makefile generated by C++ for login.cc
Configurable defines for the build script:
BIFLEX: only to be defined if the biflex-script will be used.
CLASSES: string of directory-names under which sources of classes
are found
COMPILER: "g++" for C++ sources. Do not change this, unless you're
sure you want something else.
COPT: C-options used by COMPILER
ECHO_REQUEST: ON (default) if command echoing is wanted, otherwise: set
to OFF
GDB: define if gdb-symbolic debug information is wanted
(not defined by default)
LIBS: Extra libraries used for linking
LIBPATH: Extra library-searchpaths used for linking
INTERACTIVE: define only if, in the context of BIFLEX, an interactive
scanner is wanted
NO_LIBRARY: define this if you don't want a library for the object
modules, but want to keep them in separate ./o directories
by default: not defined, so a library is used.
PROGRAM: define if a program is to be built. If not defined,
library maintenance is assumed.
(default: defined)
Current values:

//Do not change the next define unless you know what you're doing:
#define COMPILER "gcc"
// COPT: the set of C-options
#define COPT "-m486 -Wall -funsigned-char"
// CLASSES: the list of directories containing the sources of classes. E.g.,
// #define CLASSES "class1 class2"
// All class-names must be stored in one string, no string-concatenation.
// If classes are removed from the CLASSES definition or if the names
// in the CLASSES definition are reordered, the compilation should start
// again from scratch.

// Specify libs from the most specific to the most general one.
#define LIBS "rss"

// E.g., #define LIBPATH "/some/path /some/other/path" to search these paths
// apart from the default paths
#define LIBPATH "../lib"
