On 02/14/03 04:30 Ronald Landheer-Cieslak spoke thusly

if test "x$enable_ogglibs" = xyes; then

What does the "x" mean?

The "x" is just there to make sure that there is something left of the test's operator in case the variable is empty.

I can't find the "x" syntax in 'man test' or 'info test'.
Where is it explained?
