[Qt-interest] How can I remove CFLAGS -O2 using project file?

[phil prentice]

Hi
  I now understand.  Basically I can turn optimisation off by setting
  QMAKE_CFLAGS_RELEASE = -O0

  That now fixes my problem. I did not realise that QMAKE_CFLAGS_RELEASE  
modifies the -O flag according to whats set in QMAKE_CFLAGS_RELEASE. I also 
did not realise that -O0 turns off optimsation.

Thanks

Phil
