Note that I only have access to AIX 5.2 and 5.3.  Most of the macros are from public doc:

http://publib.boulder.ibm.com/infocenter/aix/v7r1/index.jsp?topic=/com.ibm.aix.files/doc/aixfiles/XCOFF.htm

It looks like I indeed get the definitions of:

+ /* Executable requires large pages for text.  */
+ #define F_LPTEXT    0x0400
+ 
+ /* Executable requires large pages for data.  */
+ #define F_LPDATA    0x0800
+ 
+ /* Archive member ignored by the linker.  */
+ #define F_LOADONLY  0x4000
+ 
+ /* Read/write sections are non-executable.  */
+ #define F_NONEXEC   0x8000
+ 

directly from the AIX headers.  But F_LPDATA is mentioned in AIX 6.1 doc for ld, so is F_LOADONLY in strip command.

F_NONEXEC is documented in:

http://www.ibm.com/developerworks/aix/library/au-appdev-aix5l.html

So only F_LPTEXT doesn't appear in IBM doc, but it appears in Valgrind code.

I can remove these macros as they aren't yet used in binutils.  Tell me what do you prefer.
