Elena Pourmal ec41266585 [svn-r13442] H5system.c file didn't include H5MMprivate.h; that caused warnings on VMS; fixed
tfilter.cpp compilation failed on VMS; fixed by casting filter_bogus to (H5Z_func_t)

Platforms tested:
	kagiso, VMS server

* Function: HDfprintf
*
* Purpose: Prints the optional arguments under the control of the format
* string FMT to the stream STREAM. This function takes the
* same format as fprintf(3c) with a few added features:
*
* The conversion modifier `H' refers to the size of an
* `hsize_t' or `hssize_t' type. For instance, "0x%018Hx"
* prints an `hsize_t' value as a hex number right justified and
* zero filled in an 18-character field.
*
* The conversion `a' refers to an `haddr_t' type.
*
* Return: Success: Number of characters printed
*
* Failure: -1
*
* Programmer: Robb Matzke
* Thursday, April 9, 1998
*
* Modifications:
* Robb Matzke, 1999-07-27
* The `%a' format refers to an argument of `haddr_t' type
* instead of `haddr_t*' and the return value is correct.

* Function: HDstrtoll
*
* Purpose: Converts the string S to an int64_t value according to the
* given BASE, which must be between 2 and 36 inclusive, or be
* the special value zero.
*
* The string must begin with an arbitrary amount of white space
* (as determined by isspace(3c)) followed by a single optional
* `+' or `-' sign. If BASE is zero or 16 the string may then
* include a `0x' or `0X' prefix, and the number will be read in
* base 16; otherwise a zero BASE is taken as 10 (decimal)
* unless the next character is a `0', in which case it is taken
* as 8 (octal).
*
* The remainder of the string is converted to an int64_t in the
* obvious manner, stopping at the first character which is not
* a valid digit in the given base. (In bases above 10, the
* letter `A' in either upper or lower case represetns 10, `B'
* represents 11, and so forth, with `Z' representing 35.)
*
* If REST is not null, the address of the first invalid
* character in S is stored in *REST. If there were no digits
* at all, the original value of S is stored in *REST. Thus, if
* *S is not `\0' but **REST is `\0' on return the entire string
* was valid.
*
* Return: Success: The result.
*
* Failure: If the input string does not contain any
* digits then zero is returned and REST points
* to the original value of S. If an overflow
* or underflow occurs then the maximum or
* minimum possible value is returned and the
* global `errno' is set to ERANGE. If BASE is
* incorrect then zero is returned.
