Description

When building the stdcxx on Cygwin I get errors like:

Now that 4.2.0 is released, set Affects Version(s) accordingly.

[Farid Zaripov]

The patch is attached.

ChangeLog:

2007-11-22 Farid Zaripov <[e-mail]>

STDCXX-585

• BAD_ALLOC_ASSIGNMENT.cpp: Don't define ~bad_alloc() when
  testing the presence of the other members to avoid multiply
  defined sybmol linker errors.

[Martin Sebor]

I assume the patch has tested successfully with all compilers on both Linux and Windows. If that's correct, let's check it in and keep a close eye on all the other platforms to see what happens and be ready to revert it if it breaks things too badly.

[Martin Sebor]

FWIW, I would have preferred to commit this on trunk only and wait for a full set of results before merging it out to 4.2.1.

[Farid Zaripov]

It seems that this patch doesn't cause any problems on the another platforms.
Closing.
