[GNC-dev] debug info

[c.holtermann at gmx.de]

Hello,

when debugging for my recent pull request #439 I needed to use
gdb. When compiling the maint branch from github I didn't have debug
information (line numbers) in gdb. I needed to add them by including
the -g flag in CMakelLists.txt. I did it only for c and not for c++.
Patch below for illustrative purposes.

Wouldn't it be good to have a command line option or environment
variable to enable that debug information for c and c++ ?

regards,

Christoph Holtermann
