while newer revisions of the c++ standard define that variables declared within for(...;...;...) are local to the loop it is still not considered portable to rely on it

I added a note to the coding guidelines.

Well, the *same* errors are in the current 5.0.20a.
cc-1101 CC: ERROR File = listener.cc, Line = 179
"i" has already been declared in the current scope.
for (int i= 0; i < num_sockets; i++)
^
cc-1548 CC: WARNING File = listener.cc, Line = 112
The transfer of control bypasses...
... the initialization of variable "i" (declared at line 120).
... the initialization of variable "i" (declared at line 179).
goto err;
^
cc-1101 CC: ERROR File = listener.cc, Line = 192
"i" has already been declared in the current scope.
for (int i= 0; i < num_sockets; i++)
^
2 errors detected in the compilation of "listener.cc".

I just verified that on IRIX 6.5 with MIPSpro Compilers: Version 7.41 the 5.0.20a source can be compiled if configured with CC=cc \ CXX=CC \ CFLAGS="-O3 -c99 -OPT:Olimit=0" \ CXXFLAGS="-O3 -c99 -OPT:Olimit=0 -LANG:exceptions=OFF \ -LANG:std=ON -LANG:libc_in_namespace_std=OFF" \ ./configure--prefix=/usr/local/mysql --localstatedir=/usr/local/mysql/data \ --libexecdir=/usr/local/mysql/bin --with-extra-charsets=complex \ --enable-thread-safe-client --enable-local-infile --disable-shared \ --with-zlib-dir=bundled --with-big-tables --with-readline \ --with-archive-storage-engine --with-innodb Now, the resulting binary doesn't work but that is another story, bug#13711.

Joerg, Please, try to compile 5.0.20a with options suggested in Kent's last comment. If you'll have no error messages like before, we can close this bug report, I think.

Ok.. it compiles. But i cant see any different flag expect the issue that i have used some exports foo=bar first. regards Joerg

Available in 5.0.25 and soon in 5.1.12-beta.
