gcc 4.5.0 stddef.h clobbers __size_t with #define, breaks VMS (code already
avoids similar on FreeBSD)#8207;
VMS decc$types.h:
typedef unsigned int __size_t;
but with GCC 4.5.0 this preprocesses as:
typedef unsigned int ;
and there are ensuing errors e.g. when compiling

VMS headers use __int64.
I hack mine up with
#ifdef __GNUC__
#ifndef __int64
#define __int64 long long

It seems to me gcc should recognize __int64, at least on VMS and Win32 targets.

Note that in all those patches, the open curly brackets are in the wrong place:
in GCC, C++ runtime included, must *always* follow a newline. Just stylistic
issues, of course.

The reference is created at df-scan.c:2940 in df_ref_record.
reg (as well as *loc) passed to that function is SImode reg 112 (in0), i.e. a

Reading the autogenerated API documentation page [1], there are the following
typedefs starting with s:
* seconds : std::chrono
* sregex_token_iterator : std
* ssub_match : std
* streambuf : std
* streamoff : std
* streampos : std
* streamsize : std
