Again on Windows support (2)

[carlo\.bramix]

Hello,
after a while I decided to take again guile and I tried to continue the test on 
mingw+msys.
In one of the messages posted in thread "Again on Windows support" it has been 
said to me to put in ~/.guile:

  (debug-enable 'backtrace)
  (debug-set! depth 80)

Since I was not able to do this test with .guile, I tried to modify directly 
the values in the sources.
Into libguile/eval.c I temporally changed the initialization of some 
scm_debug_opts[] as:

{ SCM_OPTION_INTEGER, "depth", 80, "Maximal length of printed backtrace." },
{ SCM_OPTION_BOOLEAN, "backtrace", 1, "Show backtrace on error." },
{ SCM_OPTION_BOOLEAN, "debug", 1, "Use the debugging evaluator." },

I hope I changed the right points.
After that, I recompiled and I got this result on console:

Backtrace:

make[3]: *** [guile-procedures.texi] Error 1

I also did the tests suggested to me in the past (first test does not print 
anything):

$ ./pre-inst-guile -c 1

$ ./pre-inst-guile -c '(display "foo")'
Backtrace:
In unknown file:

   ?: 1* [eval-string "(display"]

I hope you may have an idea about what it is happening.

Sincerely,

Carlo Bramini.
