Description:
Compiling MySQL (4.1 or 5.1) with Intel icc 9.0 throws the following warning when compiling sql_yacc.cc:

Note: The following compile may take a long time.
If it fails, re-run configure with --with-low-memory
icpc -DMYSQL_SERVER -DDEFAULT_MYSQL_HOME="\"/usr/local/mysql\"" -DDATADIR="\"/usr/local/mysql/data\" " -DSHAREDIR="\"/usr/local/mysql/share/mysql\"" -DHAVE_CONFIG_H -I. -I. -I.. -I../innobase/include -I../include -I../include -I../regex -I.     -O3 -DDBUG_OFF -O1 -ip   -fno-implicit-templates -fno-exceptions -fno-rtti  -c sql_yacc.cc
icpc: Command line warning: overriding '-O3' with '-O1'
sql_yacc.cc(12098): warning #1357: optimization disabled due to excessive resource requirements; contact Intel Premier Support for assistance

How to repeat:
Take a 4.1 or 5.1 source tarball and configure/compile it with the following options:

CC=icc CFLAGS="-O1 -ip" CXX=icpc CXXFLAGS="-O1 -ip"  ./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-readline --with-embedded-server --with-archive-storage-engine --with-innodb

Observe the above warning during the compilation of sql_yacc.cc

Just checked the build logs from 5.0.40 and it's still there.

This is not a bug in MySQL.
