The "correct" way to do an XFree86 debug build

[Harold Hunt]

Alan,

Our previous method of doing a debug build of XFree86 was to add -g to
xc/cf/cygwin.cf/OptimizedCDebugFlags.

I'm woking on documenting the Cygwin/XFree86 build process and I'd like to
ensure that our method is correct.  Should we also be defining DEBUG and
SMART_DEBUG on xc/cf/cygwin.cf/StandardDefines?

Furthermore, is there a simple switch that we should be toggling to enable a
full debug build?

I'd like to have as correct an answer as possible, so that we don't have to
answer these questions again in the future :)

Thank you,

Harold
