Re: gcc-3.0 pre and mem_fun()

Hi,

I forgot to post my configuration:

bash-2.05$ gcc-3.0 -v
Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0/specs
Configured with: ../../src/gcc/gcc/configure --enable-languages=c,c++ 
--infodir=/share/info --mandir=/share/man --enable-shared --with-gnu-as 
--with-gnu-ld --with-system-zlib --enable-long-long --enable-nls --without-x
 --without-included-gettext --disable-checking --enable-threads=posix 
--enable-version-specific-runtime-libs 
--disable-libgcj : (reconfigured) ../../src/gcc/gcc/configure 
--enable-languages=c,c++ --infodir=/share/info --mandir=/share/man
--enable-shared --with-gnu-as --with-gnu-ld --with-system-zlib 
--enable-long-long --enable-nls --without-x --without-included-gettext 
--disable-checking --enable-threads=posix --enable-version-specific-runtime-libs
--disable-libgcj
Thread model: posix
gcc version 3.0 20010526 (prerelease)

I don't know how to get information about my library version/configuration at 
the moment. Please tell me ...

bye, Ralf
