Config::CONFIG['srcdir'] in cvs HEAD

[Paul Brannan]

I noticed that this variable went away somewhere in 1.9; it seems to be
present in 1.6 and 1.8. In 1.9, there is Config::CONFIG['abs_srcdir'],
but its value is not useful to me:

CONFIG["abs_srcdir"] = "$(ac_abs_srcdir)"
CONFIG["abs_top_srcdir"] = "$(ac_abs_top_srcdir)"
...

I'm not sure if there's something wrong with the code that expands these
variables or the the code that generates rbconfig.rb. Other variables
like CONFIG['LIBRUBY'] seem to be okay.

FWIW, I'm using autoconf 2.59 (also tried with 2.57; same results).

Questions:

1. Why has CONFIG['srcdir'] gone away?

2. Why is CONFIG['abs_srcdir'] set to the value it is? Will this be
fixed?

Thanks,

Paul

Because it has no meanings after installation.

Just not noticed. Variables whose value starts with ac_ are
all useless?
