[Bug fortran/36215] [4.4 regression] Fortran bootstrap fails on _abs_c4.F90

I forgot to allocate enough memory for wide strings instead of regular string
while unescaping filenames in preprocessor directives, which is fixed by the
following patch:

Index: scanner.c
===================================================================
--- scanner.c   (revision 135088)
+++ scanner.c   (working copy)
@@ -1570,7 +1570,7 @@ preprocessor_line (gfc_char_t *c)
   if (unescape)
     {
       gfc_char_t *s = wide_filename;
-      gfc_char_t *d = gfc_getmem (c - wide_filename - unescape);
+      gfc_char_t *d = gfc_get_wide_string (c - wide_filename - unescape);

       wide_filename = d;
       while (*s)


This removes all valgrind errors under linux and allows compilation of
preprocessed files on mingw (bootstrapped is not yet finished, but it compiled
_abs_c4.F90 OK and is proceeding further).
