I have been using 20090605-cvs in my daily work (on F10 -- using system 
Tcl, Tk, etc), and I have not noticed your problems. Are you using the 
supplied versions of Tcl or the system versions? [i.e., Are src/tcl, 
src/tk, and src/itcl in your source tree?]

Try opening the debug window or enable logging (see the README). That 
might provide some "insight" into what may be going wrong.

Remind me: what's your target's triple? arm-what? What target are you 
using to run executables, simulator, a board?

Out of curiosity, if you open a console window in insight (when your 
target is stopped at a breakpoint) and type "tk 
gdb_target_has_execution" what does it return?

I have never used mingw; I am glad you tried this under cygwin...

Tonight I updated to CVS HEAD and rebuilt the whole thing. It took 
several hours (I only have a 500MHz Pentium III that runs Win2k -- I 
*really* got to set up a virtualized host!), but my build succeeded.

I updated my cygwin installation immediately prior to configuring, 
building, and installing:

$ CFLAGS="-g" ../src/configure 
--prefix=/home/keiths/sources/insight/head/built
[snip]
$ make all-gdb install-gdb
[snip]

[I set the CFLAGS to "-g" so that I can debug the resultant executable, 
if I need to. You need not specify it.]

There must be something magical about my machine that it works every 
time... :-P

Line 66 of tclUnixInit.c is (and the accompanying comment):

/*
  * Directory in which to look for packages (each package is typically
  * installed as a subdirectory of this directory).  The symbol is
  * defined by Makefile.
  */

static char pkgPath[sizeof(TCL_PACKAGE_PATH)+200] = TCL_PACKAGE_PATH;

What does your Makefile say the value of TCL_PACKAGE_PATH is? In my 
build (cygwin/Makefile), this is defined:

TCL_PACKAGE_PATH = NONE/lib /home/keiths/insight/head/built/lib

I configured with --prefix=/home/keiths/insight/head/built, so this 
looks okay. Right below this is the Makefile portion that uses this:

AM_CFLAGS = -DTCL_LIBRARY='"$(TCL_LIBRARY)"' 
-DTCL_PACKAGE_PATH='"$(TCL_PACKAGE_PATH)"'

Does this look the same in your Makefile?

For this file on my cygwin box, the following build command was executed:

gcc -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" 
-DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" 
-DPACKAGE=\"libtcl_cygwin\" -DVERSION=\"8.4\" -DHAVE_GETCWD=1 
-DHAVE_OPENDIR=1 -DHAVE_STRSTR=1 -DHAVE_STRTOL=1 -DHAVE_TMPNAM=1 
-DHAVE_WAITPID=1 -DNO_VALUES_H=1 -DHAVE_UNISTD_H=1 -DUSE_TERMIOS=1 
-DHAVE_SYS_TIME_H=1 -DTIME_WITH_SYS_TIME=1 -DHAVE_ST_BLKSIZE=1 
-DSTDC_HEADERS=1 -DNO_UNION_WAIT=1 -DNEED_MATHERR=1 -DRETSIGTYPE=void 
-DHAVE_SIGNED_CHAR=1 -DHAVE_SYS_IOCTL_H=1 -DHAVE_TM_ZONE=1 -I. 
-I../../../src/tcl/cygwin  -I../../../src/tcl/cygwin/../generic 
-DTCL_LIBRARY='"/home/keiths/sources/insight/head/built/share/tcl8.4"' 
-DTCL_PACKAGE_PATH='"NONE/lib 
/home/keiths/sources/insight/head/built/lib"' -g -mno-win32  -c 
../../../src/tcl/cygwin/../unix/tclUnixInit.c

As you can see, both our builds have the define for TCL_LIBRARY (in your 
build it is not set correctly for some reason -- this value is generated 
by configure), yet only my build defines TCL_PACKAGE_PATH -- in yours it 
is missing for some reason. Did you paste the entire command?
