For explanation, see comments and text in the new file libguile/measure-hwm.scm. * .gitignore: Add libguile/stack-limit-calibration.scm. * check-guile.in: Load libguile/stack-limit-calibration.scm. * configure.in: Add AC_CONFIG_FILES to generate test-use-srfi from test-use-srfi.in. * libguile/Makefile.am (TESTS, TESTS_ENVIRONMENT, stack-limit-calibration.scm): New targets, so that `make check' calibrates the stack limit before running the Guile test suite. * libguile/measure-hwm.scm: New file, calibrates stack limit for `make check'. * libguile/stackchk.c (scm_sys_get_stack_size): New primitive. * libguile/stackchk.h (scm_sys_get_stack_size): New primitive (declaration). * test-suite/standalone/test-use-srfi: Renamed test-use-srfi.in, so that ./configure can fill in variables in it. * test-suite/standalone/test-use-srfi.in: Load libguile/stack-limit-calibration.scm.
