put automatic suffix on symbol of variables of module c

[david bonnin <davidbonnin@xxxxxxx>]

Hello,

i have a closed software that convert .jpg in .c file.
This .c file, it allways the same variables at eatch generated time.

The probleme is that i have 10 files in this type.(so_mylogo.c, 
so_mylogo_hd.c).
But, i can't compile in same project because same symbol in multipe 
files.......(and not like  char my_var_so_mylogo[JPG_LENGTH]  char 
my_var_so_mylogo_hd[JPG_LENGTH])

What can i do?

Is it possible when i compile so_mylogo.c , gcc put an automatic suffix 
"so_mylogo" at eatch symbol/variable?

Thanks for help.
