From: Mumit Khan <khan@xraylith.wisc.edu>
Platform : i386-pe (mingw32, cygwin32, etc)
binutils : everything upto and including 980830
compiler : egcs-1.1
The following C++ code shows an odd problem with switching named linkonce
sections within the same object file, and such code shows up in C++ with
jump tables. Essentially, we lose the linkonce directive after the switch.
The appended patch appears to fix this problems.
If I add a ``.linkonce discard'' to the second .section .text$func__Fc
when it switches back, the linkonce is preserved, but the final executable
crashes.
I doubt the patch would fix this problem.
