This is done by defining the Gnulib module indicator variables per gnulib-tool invocation. So that a generated .h file is no longer influenced by the set of modules used in other gnulib-tool invocations. * gnulib-tool (func_compute_include_guard_prefix): Set module_indicator_prefix. (func_emit_lib_Makefile_am, func_emit_tests_Makefile_am): Use it to modify $(GNULIB_*) variable references in the Automake snippets. (func_emit_initmacro_start): Push macro definitions for GL_MACRO_PREFIX and GL_MODULE_INDICATOR_PREFIX. (func_emit_initmacro_end): Pop these macro definitions. * pygnulib/GLConfig.py (GLConfig.getIncludeGuardPrefix): New method. * pygnulib/GLEmiter.py (GLEmiter.initmacro_start): Push macro definitions for GL_MACRO_PREFIX and GL_MODULE_INDICATOR_PREFIX. (GLEmiter.initmacro_end): Pop these macro definitions. (GLEmiter.lib_Makefile_am, GLEmiter.tests_Makefile_am): Use the module indicator prefix to modify $(GNULIB_*) variable references in the Automake snippets. * m4/gnulib-common.m4 (gl_MODULE_INDICATOR_INIT_VARIABLE, gl_MODULE_INDICATOR_SET_VARIABLE): Use the value of GL_MODULE_INDICATOR_PREFIX. * m4/arpa_inet_h.m4: Use new idiom for header files that contain references to Gnulib module indicator variables: - Define the main macro through AC_DEFUN_ONCE. - Define a macro gl_*_H_REQUIRE_DEFAULTS that initializes the Gnulib module indicator variables (each prefixed with GL_MODULE_INDICATOR_PREFIX). - Invoke this macro in the gl_*_MODULE_INDICATOR macro. * m4/ctype.m4: Likewise. * m4/dirent_h.m4: Likewise. * m4/fcntl_h.m4: Likewise. * m4/fnmatch_h.m4: Likewise. *
