 Tested with 3 gcc versions:
 
 seb@myp233:~/test/cp$ gcc-2.95 -v
 Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs
 gcc version 2.95.4 20011002 (Debian prerelease)
 
 seb@myp233:~/test/cp$ gcc-3.0 -v
 Reading specs from /usr/lib/gcc-lib/i386-linux/3.0.4/specs
 Configured with: ../src/configure -v --enable-languages=c,c++,java,f77,objc --prefix=/usr --infodir=/share/info --mandir=/share/man --enable-shared --with-gnu-as --with-gnu-ld --with-system-zlib --enable-long-long --enable-nls --without-included-gettext --disable-checking --enable-threads=posix --enable-java-gc=boehm --with-cpp-install-dir=bin --enable-objc-gc i386-linux
 Thread model: posix
 gcc version 3.0.4
 
 seb@myp233:~/test/cp$ gcc-3.2 -v
 Reading specs from /usr/lib/gcc-lib/i386-linux/3.2.1/specs
 Configured with: /mnt/data/gcc-3.1/gcc-3.2-3.2.1ds2/src/configure -v --enable-languages=c,c++,java,f77,proto,objc,ada --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-gxx-include-dir=/usr/include/c++/3.2 --enable-shared --with-system-zlib --enable-nls --without-included-gettext --enable-java-gc=boehm --enable-objc-gc i386-linux
 Thread model: posix
 gcc version 3.2.1 20020924 (Debian prerelease)
 
 
 Results for the original bug example:
 
 seb@myp233:~/test/cp$ gcc-2.95 -c pr7679.cc
 pr7679.cc: In method `double receptors::occupancy(int)':
 pr7679.cc:14: parse error before `;'
 Stops shortly.
 
 seb@myp233:~/test/cp$ gcc-3.0 -c pr7679.cc
 pr7679.cc: In member function `double receptors::occupancy(int)':
 pr7679.cc:14: parse error before `;' token
 Loops indefinitely.
 
 seb@myp233:~/test/cp$ gcc-3.2 -c pr7679.cc
 pr7679.cc: In member function `double receptors::occupancy(int)':
 pr7679.cc:14: parse error before `;' token
 Loops indefinitely.
 
 
 
 Also tested:
 
 struct f
 {
   int oo()
   {
     return (2;
   }
 };
 
 Slightly simpler to analyse than the original bug example,
 and produces the same infinite loop.
 
 
 Note that gcc-3.2 stops correctly when it gets only the function declaration:
 
   int oo()
   {
     return (2;
   }
