Question on applicability of --with-gnu-*

[NightStrike <nightstrike@xxxxxxxxx>]

--with-gnu-as
--with-gnu-ld

These options, according to the manual, apply to 'i386-any-sysv'.  Do
they also apply to i686-pc-mingw32?

Also, if binutils is the only assembler installed on the system, and I
am compiling using --with-sysroot, and I don't specify --with-gnu-as
and -ld, and I *am* compiling for a mingw32 target, do these options
have any effect?
