[Bf-committers] Compiler flags

[Giuseppe Ghibò]

Is there a way to specify in user-config.py the
compiler flags without having to list them enclosed into
[ '...', '...', ... ], i.e. something like:

FLAGS = '-O2 -funsigned-char'

rather than

FLAGS = [ '-O2', '-funsigned-char' ]

Furthermore which one between this pair is really used for
setting the compiler flags into user-config.py?

CCFLAGS and CXXFLAGS

or

REL_CFLAGS and REL_CCFLAGS?

Thanks
Bye
Giuseppe.
