|  # Identity of this package.
|  PACKAGE_NAME='am__sinclude'
|  PACKAGE_STRING='am__sinclude 1.0'
|but on
|  AC_INIT([am__include], [1.0])
|you get
|  # Identity of this package.
|  PACKAGE_NAME='am__include'
|  PACKAGE_TARNAME='am--include'
|  PACKAGE_STRING='am__include 1.0'
|Note the definition of PACKAGE_TARNAME in both cases.  

Heck, I never thought about this.

Well, I think it is high time to disable include and sinclude from
Autoconf.  That's too dangerous.  Paul, do we agree?  m4_include and
m4_sinclude are available since 2.50, and people are not supposed to
use include and sinclude.  Do your greps reveal some people still use

As an aside.  I personnally consider it is a flawn in the specs of M4:
IMNSHO, something like

        patsubst([foo], [foo], [dnl])

should return a *quote* string, i.e., [dnl], not dnl.  That's the
bottom line of our problem.  I would really love to see a means to
educate GNU M4 in this regard.  I don't really care how: be it a new
series of macros, a new option, a new name, whatever.  I just want its
text processing macros to return a quoted string.
