## Generate `glibconfig.h' in two cases
## 1. `config.status' is run either explicitly, or via configure.
## Esp. not when it is run in `Makefile' to generate makefiles and
## config.h
## 2. CONFIG_OTHER is set explicitly
##
## Case 1 is difficult. We know that `automake' sets one of
## CONFIG_FILES or CONFIG_HEADERS to empty. This heuristic works
## only when AM_CONFIG_HEADER is set, however.
