Re: [patch 1/4] libdecnumber support

[Daniel Jacobowitz <drow@false.org>]

I'll review all these now.  Before you check them in, though, give
me a chance to get libdecnumber merged into the src repository.  It
shouldn't take long.

What do you need ctype.h for?  That will tell me whether you really
want ctype.h or libiberty's locale-independent safe-ctype.h.

defs.h should always be first.

endian.h is not portable.  You should probably use the autoconf macro
AC_C_BIGENDIAN.

You didn't include anything that would give you uint8_t; use
gdb_byte.  Also we never use malloc, only xmalloc.  Or you could avoid
the allocation by using gdb_byte dec[16].

Spaces and tabs mixed up?  xfree, like xmalloc.

Space before parentheses please.

This comment doesn't belong here.  The file is part of GDB once the
patch is applied.

Don't include standard headers here; stick to what defs.h provides.
Just as well, since neither string.h nor stdint.h is portable.
