#3004 Solaris tclConfig.sh : mystery value

[Don Porter]

after configuring Tcl on Solaris,
I see in tclConfig.sh:

TCL_COMPAT_OBJS=' fixstrtod$U.o'

What is the "$U" doing there?

Other code that reads tclConfig.sh
doesn't know how to make sense of it.

All we say is "AC_LIBOBJ([fixstrtod])", so that is added by
autoconf. If that's not in 8.4 as well ... ???

autoconf-2.57 garbage?

configure scripts for Tcl 8.4.x
are still generated by autoconf-2.13

Link claims $U is put in there
for automake.

Not all autoconf users are gonna
use automake, stupid bastards!

"When asked for automatic de-ANSI-fication, Automake needs
LIBOBJS'ed filenames to have `$U' appended to the base names. "

Any idea how we can stop
asking "for automatic de-ANSI-fication" ?

autoconf goes to great lengths to prevent you from doing
this, but I think this incantation will work

AC_CONFIG_COMMANDS_PRE([
eval `echo LIB OBJS | sed 's/ //'`="\`echo
\"$ac_libobjs\" | sed 's/\$U//g'\`"
])

A reply on the autoconf mailing
list suggests a few possible workarounds:

define([_AC_LIBOBJS_NORMALIZE],[])
AC_OUTPUT

or

save_LIBOBJS=$LIB@&t@OBJS
AC_CONFIG_COMMANDS_PRE([[LIB@&t@OBJS=$save_LIBOBJS]])
AC_OUTPUT

Here's a patch implementing the
first workaround. Works for me.
