Summary: configure crashes with bash 3.1 in two macros

Initial Comment:
I attempted to build tcl 8.4.12 on my Linux system with
a bash 3.1 shell.  The configure script failed as follows:

checking system version (for dynamic loading)...
../configure: line 7653: syntax error near unexpected
token `)'
../configure: line 7653: `      OSF*)'

I tracked the problem down to the following line (2484
in the shipped configure script):

  system=MP-RAS-`awk '{print }' /etc/.relid'`

Note the extra ' just before the final back-quote. This
is the cause of the problem.  Later on, the same issue
appears again at line 7640.

The two occurrences of the offending line appear to
come from the macros SC_CONFIG_CFLAGS and
SC_BLOCKING_STYLE, defined in the Tcl-specific autoconf
macros in unix/tcl.m4. It looks like a typo to me.
Removing the extra quote lets the script run correctly.

Since 8.4.12 presumably would not have shipped with a
bad configure script, I'm assuming that older versions
of bash were less picky about quote parsing.

For additional info, please contact me at

Hello,
I confirm this problem (under debian)

v 8.4.11

Line 2133 & 7611, configure have extra quote '
after "relid" word.

bash with or without bug, it is ALSO a syntax error
in tcl configure script

system=MP-RAS -`awk '{print }' /etc/relid' `
is false
system=MP-RAS -`awk '{print }' /etc/relid `
is correct

Error appears twice.

Thank you for correcting this because many 'builds' are
broken because of this typo!


Bye
Franck

Patch 001 for bash 3.1 was posted just recently, and it
includes fixes for some parsing problems introduced in 3.1.
 Have you tried that patch to see if it fixes the issue
you're running into?
