### build_subdirs is the list of directories we actually want to
### build. It's not equivalent to existingdirs: if we can't find the
### Tcl libraries, then we don't want to build in gtcltk-lib.
###
### So why can't we just forget about gtcltk-lib altogether, and
### delete it from existingdirs, in that case? Well, in order for
### 'make dist' to work, we still need to configure gtcltk-lib, and
### the top-level Makefile needs to know it exists,
build_subdirs="${existingdirs}"
### Decide which directories to build; remove the ones we don't want
### from build_subdirs.
### On some systems, the Tcl library contains references to
### functions in the dynamic linker library, -ldl, so we may need
### to include that.
AC_CHECK_LIB(dl, dlopen)
### Use gtcltk-lib only if we seem to have Tcl installed on the
### system. We really should check for Tk as well, but that involves
### finding all the X libraries that we need to do a complete link.

### Write the list of survivors, the directories we do want to build,

### run on their own.
