+ and return the result as a struct expression pointer.
+ That structure contains arithmetic operations in reverse polish,
+ with constants represented by operations that are followed by special data.
+ See expression.h for the details of the format.
+ What is important here is that it can be built up sequentially
+ during the process of parsing; the lower levels of the tree always
+ come first in the result.
+
+ Note that malloc's and realloc's in this file are transformed to
+ xmalloc and xrealloc respectively by the same sed command in the
+ makefile that remaps any other malloc/realloc inserted by the parser
+ generator. Doing this with #defines and trying to control the interaction
+ with include files (<malloc.h> and <stdlib.h> for example) just became
+ too messy, particularly when such includes can be inserted at random
+ times by the parser generator. */

+/* FIXME: there are still 21 shift/reduce conflicts
+ Other known bugs or limitations:
+ - pascal string operations are not supported at all.
+ - there are some problems with boolean types.
+ - Pascal type hexadecimal constants are not supported

+
+ Some object/debugging file formats (DWARF version 1, COFF, etc) do not

+ DWARF version 2, etc) do define fundamental types. For the formats which
+ don't provide fundamental types, gdb can create such types using this
+ function.
+
+ FIXME: Some compilers distinguish explicitly signed integral types
+ (signed short, signed int, signed long) from "regular" integral types
+ (short, int, long) in the debugging information. There is some dis-
+ agreement as to how useful this feature is. In particular, gcc does
+ not support this. Also, only some debugging formats allow the
+ distinction to be passed on to a debugger. For now, we always just
+ use "short", "int", or "long" as the type name, for both the implicit
+ and explicitly signed types. This also makes life easier for the
+ gdb test suite since we don't have to account for the differences
+ in output depending upon what the compiler and debugging format
+ support. We will probably have to re-examine the issue when gdb
+ starts taking it's fundamental type information directly from the
