	None of these problems you are reporting are GCC code generation
bugs, they are collect2 exporting bugs.  AIX has an export list for a
reason and GCC collect2 is subverting that policy.  Some symbols are
special and collect2 is blindly re-exporting them.

	[I cannot send email directly to Andrey from this address for some
reason and none of my replies to egcs have appeared back on the list
although I am receiving other egcs mailings.]
