PS: I don't understand, what the trouble was with debugging? Old code was
includes conditional part when DEBUG is defined, new code includes code only
when DEBUG is defined AND not zero. Ie. -DDEBUG now not enough to include
those conditional part.
I'm confused. How does #ifdef DEBUG (the new code) require DEBUG to be defined and not zero?
The issue here is that when I converted an #if 1 to be debug only
code I forgot to change the #if to #ifdef.
On a tangential [only slightly related] note, for debug code I want in the source but
almost never compiled (something that helped track down a specific issue, but
generally not needed for a debug build), should I used
#ifdef DDEBUG ... #endif
or simply
#if 0 ... #endif
or
#ifdef <?? suggestions ??> ... #endif
Thanks, Jeremy
