GDB/Cygwin source path problem fix suggestion

[Kristian Otnes]

Eh, I guess one should use MAX_PATH + 1, so the fix would be:



/* Start recording information about source code that came from an
   included (or otherwise merged-in) source file with a different
   name.  NAME is the name of the file (cannot be NULL), DIRNAME is
   the directory in which it resides (or NULL if not known).  */

/* START FIX by Kristian Otnes, 2003-09-28, see details below */
#ifdef __CYGWIN__
#include <windows.h>	    	/* For MAX_PATH...  */
#include <sys/cygwin.h>		/* For cygwin_conv_to_...  */
#endif
/* END FIX by Kristian Otnes, 2003-09-28 */

void
start_subfile (char *name, char *dirname)
{
  struct subfile *subfile;

  /* START FIX by Kristian Otnes, 2003-09-28 */
  /* In case the symbol info contained Windows type paths (c:\...) we */
  /* should convert to Posix style path. Otherwise there might be */
  /* problems later with opening source files in the debugger. */
#ifdef __CYGWIN__
  char *_dirname;
  char *_name;

  /* 'name' will typically not be a full path, but it doesn't hurt to */
  /* convert it to Posix style... */
  if (name)
  {
     _name = alloca(MAX_PATH + 1);
     cygwin_conv_to_posix_path(name, _name);
     name = _name;
  }

  if (dirname)
  {
     _dirname = alloca(MAX_PATH + 1);
     cygwin_conv_to_posix_path(dirname, _dirname);
     dirname = _dirname;
  }
#endif
  /* END FIX by Kristian Otnes, 2003-09-28 */

  /* See if this subfile is already known as a subfile of the current
     main source file.  */
