The "-fast" option expands to many other options involving optimization. From
the Sun Studio 12 man page for cc:
<quote> These options are turned on for -fast:
-fns (SPARC, x86)
-fsimple=2 (SPARC, x86)
-fsingle (SPARC, x86)
-nofstore (x86)
-xalias_level=basic (SPARC, x86)
-xbuiltin=%all (SPARC, x86)
-xdepend (SPARC, x86)
-xlibmil (SPARC, x86)
-xlibmopt (SPARC)
-xmemalign=8s (SPARC)
-xO5 (SPARC, x86)
-xprefetch=auto,explicit (SPARC)
-xregs=frameptr (x86)
-xtarget=native (SPARC, x86)
</quote>
One (or more) of those is causing your call to "memset()" to be replaced with a
call to "_memset()".
You can probably add those options to your build one at a time until the
problem appears.
