GNU C version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release).

2.95 says,
nathan@manao:610>g++ -c -W -Wall spiteri.C 
spiteri.C: In method `void c<T>::f()':
spiteri.C:8: parse error before `3'

when one uses `__typeof__', it compiles without error.
The non-template equivalent gives a more informative diagnostic,
nathan@manao:612>g++ -c -W -Wall spiteri.C 
spiteri.C: In method `void c::f()':
spiteri.C:8: implicit declaration of function `int typeof(...)'
spiteri.C:8: parse error before `3'
