Re: GNU ld on x86 Solaris

|     ld.new: foo: Not enough room for program headers (allocated 5, need 6)

A program header is describes a region of memory to the dynamic linker (IMHO
this is a wart in ELF, that there are two different ways of describing memory,
sections being the other).  In any case, for other ELF x86 systems, BFD
believes their will be five regions for programs that contain references to
shared libraries:

   1)	Program header region that contains the program headers themselves;

   2)	The interpreter region that points to the interpreter to invoke to
	start the program;

   3)	The read-only, execute enabled text section;

   4)	The read/write, execute disabled data section;

   5)	The data passed to the dynamic loader.

If BFD claims it needs 6 tables, then you have an extra section that must be
accounted for (such as r/w data in the middle of r/o data).
