the msvc7 options for  sse  are  /arch:SSE

not sure about gcc,  but my personal notes for  mingw makefiles
has this info...  which i use as reference:

# -march=athlon64
# -march=athlon-fx
# -march=pentium-m
# -march=pentium4
# -march is deprecated, use -mtune

# -mfpmath=387   old skool
# -mfpmath=sse   new skool

# -mmmx
# -mno-mmx

# -msse
# -mno-sse

# -msse2
# -mno-sse2

# -msse3
# -mno-sse3

# -m3dnow
# -mno-3dnow

# -m32   The 32-bit environment sets int, long and pointer to 32 bits and 
generates code that runs on any i386 system.
# -m64   The 64-bit environment sets int to 32 bits and long and pointer to 
64 bits and generates code for AMD's x86-64 architecture.
