Hi!

The myconfig.h in the config subdirectory is the fallback in case you do not 
have your own myconfig.h in the source or build directory. This fallback file 
will be overwritten everytime you reconfigure Espresso, so don't do any 
modifications to config/myconfig.h.

To know what has been compiled into your Espresso, simply use the 
command "code_info", or "puts [code_info]" in a script, which will output all 
the flags that were enabled in myconfig.h. In your case, there should appear 
BOND_ANGLE_COSSQUARE.
