determining bytes read from a file.

A couple potential optimizations:

mem_var_name = options.inputfilename.replace(' ','_').replace('.','_')
No need to assign it 3 times.

>         if i != len(hex_data):

>         if i % 32 == 0:
>                 outfile_c.write("\n")

This could be re-written as such:

for x in xrange(0, len(hex_data), 32):
    output_c.write('%s\n' % ','.join(['0x%s'%''.join(['%c'%a for a in
hex_data[x:x+32][i:i+2]]) for i in xrange(0, 32, 2)]
