Revision 1.74 - (hide annotations) (download) (as text)
Mon Aug 13 16:52:13 2001 UTC (17 years, 11 months ago) by guppy
Branch: MAIN
Changes since 1.73: +5 -11 lines
File MIME type: text/x-chdr
Cleaned up the output of .status inregards to TCL ...

Instead of showing:

Using Tcl library: /usr/local/lib/tcl8.3
Tcl version: 8.3 (header version 8.3)
Tcl patchlevel: 8.3.3 (header patchlevel 8.3.3)
TCL isn't threaded

We now show:

Tcl library: /usr/lib/tcl8.3
Tcl version: 8.3.2 (header version 8.3.2)

and is TCL is threaded:

Tcl library: /usr/lib/tcl8.3
Tcl version: 8.3.2 (header version 8.3.2)
Tcl is threaded

Do we even need to show the header version?
