Cannot add certain types using C syntax

Hi!

Types that contain <> cannot be added using Add type → C syntax.

For example, you can open the library C:\Windows\System32\WinTypes.dll and load the corresponding PDB file. Then you can use Copy full type(s) to copy _tlgWrapperByVal<1> or _IMAGE_SYMBOL types. You’ll receive the following data in your clipboard:

/* 1929 */
struct __cppobj _tlgWrapperByVal<1>
{
  const unsigned __int8 Value;
};

or

/* 3104 */
struct _IMAGE_SYMBOL::<unnamed_type_N>::<unnamed_type_Name>
{
  unsigned int Short;
  unsigned int Long;
};

/* 3105 */
union _IMAGE_SYMBOL::<unnamed_type_N>
{
  unsigned __int8 ShortName[8];
  _IMAGE_SYMBOL::<unnamed_type_N>::<unnamed_type_Name> Name;
  unsigned int LongName[2];
};

/* 3106 */
struct __unaligned __declspec(align(2)) _IMAGE_SYMBOL
{
  _IMAGE_SYMBOL::<unnamed_type_N> N;
  unsigned int Value;
  __int16 SectionNumber;
  unsigned __int16 Type;
  unsigned __int8 StorageClass;
  unsigned __int8 NumberOfAuxSymbols;
};

When trying to add these types to a fresh database using Add type → C syntax, you’ll get Bad declaration.
