It seems to only be an issue with dash if I run it as './configure'.
'dash configure' is okay.

With /bin/sh -> bash, if I insert an 'echo $_' before this line in configure:
then $_ is blank.

With /bin/sh -> dash, 'echo $_' just before that line will show $_ to
be './configure'.  Therefore THISSHELL becomes './configure', which is
obviously invalid.

I'm not sure of a fix yet...
