* libguile/load.c (scm_init_load_path): If GUILE_SYSTEM_PATH is set, use that instead of the compiled-in suffix to the load path. And, as a special case, GUILE_SYSTEM_PATH= is interpreted as '(). A bit nasty. * pre-inst-guile-env.in (top_builddir): Set GUILE_SYSTEM_PATH to the empty string, if it is not set.

# Usage: pre-inst-guile-env [ARGS]
|
|
|

# This script arranges for the environment to support running Guile

# from the build tree. The following env vars are modified (but not
|
|
# clobbered): GUILE_LOAD_PATH, LTDL_LIBRARY_PATH, and PATH.
|
|
|
|
# Example: pre-inst-guile-env guile -c '(display "hello\n")'
|
|
# Example: ../../pre-inst-guile-env ./guile-test-foo
