It is a truncation of "-fno-strict-aliasing". The flag does not appear
to be described in the gcc man page, but is documented in the gcc info
page (search for "-fstrict-aliasing"). To quote the info page,
-fstrict-aliasing "allows the compiler to assume the strictest aliasing
rules applicable to the language being compiled. ..."
Cheers,
Paul.
