line 474 in otcl 1.0a3.

Aha! First off, I downloaded 1.0a*2* yesterday via the link 'newer
version of otcl 1.0a2' on
http://www-mash.cs.berkeley.edu/ns/ns-problems.html

That had led me to believe that 1.0a2 was still current, since I
thought the 'Installation problems and bug fixes' page was the most
up-to-date of all your webpages... you might want to update that link.

Building 1.0a3 on Solaris with Tcl7.6. The int parse error I describe
above is now at line 474.

gcc also complains about the C++ // comment in a .c file at line 1102,
and then complains that Tcl_Namespace and Tcl_NamespaceDeleteProc
are undeclared at lines 2027 and 2117, as before.

Attempting that, I can get libotcl.so to build, but nothing else. wish
and the rest don't turn up in the directories specified by INST_OWISH
etc.

Since ns 2.1b3 requires otcl 1.0a3, which appears to require tcl and
tk 8.0, I suppose my only option is to go build tcl/tk 8.0.
