 This code has never been handled correctly by gcc or egcs.
 Although egcs-1.1.2 accepts it, it behaves the same regardless
 of whether the template friend is declared or not, i.e.
 that template friend is silently ignored by egcs.  So this
 is actually not a regression.  I mark this report down to
 medium priority.

 This is a regression (it works) from 2.91.66:
 Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs
 gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
 
 
 It ice in gcc 2.95.3 though:
 Reading specs from /usr/lib/gcc-lib/i386-unknown-openbsd3.1/2.95.3/specs
 gcc version 2.95.3 20010125 (prerelease)
 
 It gives an error in redHat's gcc 2.96:
 Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
 gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-112)
 
 friend.cc:9: typename type `typename A<T>::B' declared `friend'
 
 Thanks,
