RE: [RFA] ARI fix: Remove asprintf in breakpoint.c

["Pierre Muller" <muller at ics dot u-strasbg dot fr>]

  With my change in gdb.base/sigstep.c
(and similar changes in gdb.base/sigXXX.c files)
and my change of gdb.exp to avoid interruption in
gdb.fortran/array-element.exp
I was able to complete a Cygwin testsuite in 45 minutes.
  A lot better than previously.

I did not use Pedro's patch to fix the
i386_skip_prologue, thus the number of failures
are still huge.

  Results are:
                === gdb Summary ===

# of expected passes            10186
# of unexpected failures        509
# of expected failures          59
# of known failures             30
# of unresolved testcases       38
# of untested testcases         8
# of unsupported tests          16
/usr/local/src/cvs/build/gdb/testsuite/../../gdb/gdb version
6.7.50-20071009-cvs -nx

gdb.pascal directory gives me just
a XFAIL for "Breakpoint 2" due to gpc problems with line information
and a KFAIL for "ptyp 'a single string'"

 Thus I should be able to test my patches locally now...
