routines to properly handle overwriting preallocated types so that

Remove unused header_file_prev_index mechanism. It was already

and use it to decide when to print the actual type name rather than
trying to invent the name of a fundamental type. This clears up the
confusion between int/long when they are the same sizes, removes one
obstacle to multi-language support (previously valprint.c thought
everything was a C type), and allows gdb to support distinctions between
explicitly and implicitly signed types when the compiler supports such
distinction in the debug output (as does every ANSI compiler I tested
except for gcc).
flags to disable use of GNU malloc/mmalloc.
* munch: Change SYSV rule to allow .text before the label,
as well as after, to work for AIX.
* gdbtypes.h: Minor clarifiction.
