I was getting something similar

http://gist.github.com/337657

when I built ruby from the e drive, with tcl installed on e:\Tcl

Judging from this line:
gcc -I. -I../../.ext/include/i386-mingw32 -I../.././include
-I../.././ext/tk -IC:/Tcl/include  -DRUBY_EXTCONF_H=\"extconf.h\"
-DHAVE_NO_LPFN_DECLS=1 -DTCL_THREADS=1 -DUSE_THREAD_ALLOC=1
-DWITH_TCL_ENABLE_THREAD=1 -O3 -g -Wall -Wno-unused-parameter
-Wno-parentheses -Wpointer-arith -Wwrite-strings -Wno-long-long  -o
stubs.o -c stubs.c

(note the -Ic:/Tcl/include --that directory doesn't exist)

that it appears to have a hard coded c drive prefix?

Anyway moving Tcl to my c drive (and putting c:\tcl\bin into the path)
appears to fix it.  irb exits appropriately, all is well except that
for some reason after a

require 'tk'

a mysterious blank window pops up, but that's a different story I suppose.

HTH and thanks for fixing this so it can compile now :)
