The first several lines about the "export" keyword should be pretty clear: "export", used to enable a separation of declaration and definition of template classes/functions, is not supported by GCC.
A common work around to avoid this deprecated keyword and still stay on top of things is to do sort of a reverse include: Provide prototypes (with normal header extension) and definitions (usually with an "impl" ext.) in distinct files as usual but include the implementation file at the end of the header file. This is necessary as template instantiation requires presence of definition so it can instantiate the template "in one go".

Another error I spotted at a quick glance is linked with the very last function. Am I right in assuming it should be a total specialization of the function above? Then it should read "template <>". Of course, also here the function's definition is missing.

Hth, Gunther

config.guess

CONFIG.GUESS(1) 						   User Commands						   CONFIG.GUESS(1)

NAME

       config.guess - guess the build system triplet

SYNOPSIS

       config.guess [OPTION]

DESCRIPTION

       The GNU build system distinguishes three types of machines, the `build' machine on which the compilers are run, the `host' machine on which
       the package being built will run, and, exclusively when you build a compiler, assembler etc., the `target' machine, for which the  compiler
       being built will produce code.

       This script will guess the type of the `build' machine.

       Output the configuration name of the system `config.guess' is run on.

   Operation modes:
       -h, --help
	      print this help, then exit

       -t, --time-stamp
	      print date of last modification, then exit

       -v, --version
	      print version number, then exit

ENVIRONMENT VARIABLES

       config.guess  might  need  to  compile  and  run  C  code,  hence it needs a compiler for the `build' machine: use the environment variable
       `CC_FOR_BUILD' to specify the compiler for the build machine.  If `CC_FOR_BUILD' is not specified, `CC' will be used.  Be sure  to  specify
       `CC_FOR_BUILD' is `CC' is a cross-compiler to the `host' machine.

	 CC_FOR_BUILD	 a native C compiler, defaults to `cc'
	 CC		 a native C compiler, the previous variable is preferred
