Tcl Library Source Code

I tried building the tcllibc library for Windows:

Windows 10
Latest MinGW release using GCC 8.1.0 installed today
Tcllib release 1.20 downloaded today
Windows critcl.exe downloaded from AK's site today

The following was echoed to the terminal screen:




D:\critcl\tcllib-1.20>D:\tcltk86-8.6.8-5.tcl86.Win7.x86_64\bin\tclsh.exe sak.tcl critcl

Note: you can ignore warnings for tcllibc.tcl, base64c.tcl and crcc.tcl.
