# Common macro setup for GNU make											#
#																			#
# Common Build Macros REQUIRED:												#
#  SRC_ROOT			- *MUST* be set to the src dir							#
#																			#
# Common Build Macros Used:													#
#  DEBUG			- Create a debug build									#
#  PROFILE			- Generates binaries which generate gprof details		#
#					  (GCC/DEBUG only)										#
#  UPROFILE			- Generates binaries which generate profile-driven		#
#					  optimization data										#
#					  (GCC/DEBUG only)										#
#  GCOV				- Generates binaries that produce gcov data				#
#					  (GCC/DEBUG only)										#
#  RELEASE			- Create a release build								#
#					  (Mutually exclusive, if both are set, RELEASE 		#
#						is cleared)											#
#  USE_UPROFILE		- Builds using information generated by UPROFILE.		#
#					  (RELEASE builds only)									#
#  DONT_CLOBBER_CC	- Do not change the default setting of CC				#
#  OBJPATH_SUFFIX	- Suffix appended to OBJPATH usefull for compiling 		#
#					  different options of the same source file				#
#  STATIC			- Create a statically linked build if possible			#
#																			#
# Common Build Macros Defined:												#
#  DELETE			- Delete files (Preferrably verbose)					#
#  MTOBJODIR		- Object output dir										#
#  OBJODIR			- Object output dir										#
#  LIBODIR			- Library output dir									#
#  EXEODIR			- Executable output dir									#
#  DEBUG			- Set for debug builds									#
#  RELEASE			- Set for release builds								#
#					  One of DEBUG or RELEASE is always set!				#
#  QUIET			- Target command prefix to show/not show commands		#
#  					  (Toggled off by setting VERBOSE)						#
#  CFLAGS			- Common C and C++ compiler flags						#
#  CCFLAGS			- C specific compiler flags								#
#  CXXFLAGS			- C++ specific compiler flags							#
#  LDFLAGS			- Linker flags											#
#  CC				- C compiler											#
#  CXX				- C++ compiler											#
#  EXEFILE			- Executable file extension (Includes .)				#
#  OFILE			- Object file extension (Includes .)					#
#  SOFILE			- Shared object (DLL) file extension (Includes .)		#
#  LIBFILE			- Static library file extension (Include .)				#
#  LIBPREFIX		- Prefix to library filename							#
#  LIBS				- Library names	(Appropriate for dependencies)			#
#  LIB_LDFLAGS		- Libraries appropriate for link command-line usage		#
#  COMPILE_MSG		- Message saying a target is being compiled				#
#  DIRSEP			- The directory seperator this system likes most		#
#  VERSION			- Synchronet version number in MAJOR.MINOR format		#
#					  (Numeric ONLY)										#
#  OUTPUT			- Compiler flag specifying output filename				#
#  LOUTPUT			- Linker flag specifying output filename				#
#  XPDEV_SRC		- Path to xpdev											#
#  UIFC_SRC			- Path to uifc											#
#  CIOLIB_SRC		- Path to ciolib										#
#  SMBLIB_SRC		- Path to smblib										#
#  MT_CFLAGS		- CFLAGS for building MT objects						#
#  MT_LDFLAGS		- LDFLAGS for linking MT targets						#
#  UL_PRE			- Use Library prefix (*nix is -l)						#
#  UL_SUF			- Use Library siffix (bcc is .lib)						#
#																			#
# Common Targets Defined:													#
#  Implicit C and C++ targets												#
#  "clean" target															# 
#  Output directory targets													#
