"Commons" are tentative definitions in a global scope, like this:

int x;

The meaning of a common is ambiguous. It may be a true definition:

int x = 0;

or it may be a declaration of a symbol defined in another file:

extern int x;

Use the -fno-common option to force all commons to become true

definitions so that the linker can catch multiply-defined symbols.

Also, common symbols are not allowed with Darwin dynamic libraries.

The system sqlite library in the latest version of Mac OS X often becomes

newer than the sqlite library in NSS. This may result in certain Mac OS X

system libraries having unresolved sqlite symbols during the shlibsign step

of the NSS build when we set DYLD_LIBRARY_PATH to the NSS lib directory and

the NSS libsqlite3.dylib is used instead of the system one. So just use the

system sqlite library on Mac, if it's sufficiently new.
