>Description:
While trying to cross-compile insight on a Debian Lenny i386 host with the mingw32 compiler, compilation fails with the following error:

i586-mingw32msvc-gcc -c -g -O2 -D__USE_MINGW_ACCESS -Wall -Wconversion  -I"../../../../insight-6.8-111/\

>How-To-Repeat:

>Fix:
It turns out that the RC variable in tcl/win/Makefile is not set. Forcing RC to "i586-mingw32msvc-windres" fixes the problem. The very same error occurs on tk/win/Makefile
Tried to gather some debugging traces in the "configure" script:

+ set dummy windres
+ ac_word=windres
+ echo 'configure:2885: checking for windres'
+ echo -n 'checking for windres... '
checking for windres... + test '' = set
+ test -n ''
+ as_save_IFS='
'
+ IFS=:
+ for as_dir in '$PATH'
+ IFS='
'
+ test -z /usr/local/bin
+ for ac_exec_ext in ''\'''\''' '$ac_executable_extensions'
+ test -f /usr/local/bin/windres
+ for as_dir in '$PATH'
+ IFS='
'
+ test -z /usr/bin
+ for ac_exec_ext in ''\'''\''' '$ac_executable_extensions'
+ test -f /usr/bin/windres
+ for as_dir in '$PATH'

+ test -z /bin
+ for ac_exec_ext in ''\'''\''' '$ac_executable_extensions'
+ test -f /bin/windres
