 -O also turns on -fomit-frame-pointer on machines where doing so
does not interfere with debugging.

Oh!

 However, in ATLAS for cygwin gives optimizing code
-fomit-frame-pointer -mfpmath=387 -O2

I have experienced in gnuplot.exe by Gcc-4.3.0-dw2 MInGW-TDM with '-O3' did 
hang up but that with 
'-O3 -fomit-frame-pointer' hanged up.

Thus on windows 'where doing so does not interfere with debugging.' might be 
the case.
