PROGMEM, const and avr-gcc 4.8.1 / Arduino 1.5.7 [patch]

[GoogleCodeExporter]

Arduino 1.5.7 / avr-gcc 4.8.1 reports multiple:
error:  variable ... must be const in order to be put into read-only section by 
means of ‘__attribute__((progmem))’

The fix is to make the variable 'const'. Patch below.

What version of the product are you using? On what operating system?
glcd-v3-20111205
Arduino 1.5.7 (which includes avr-gcc 4.8.1)
OS X 10.9.4

Please provide any additional information below.

Original issue reported on code.google.com by b...@bdlow.net on 24 Jul 2014 at 10:13

I'm assuming this showed up when trying to use the library on the new Arduino 
1.5.7 IDE?

As an FYI, I'm no longer maintaining this code and haven't been for quite some 
time.
Michael may jump in to make some updates.

In the mean time you may want to have a look at another library that I am 
maintaining: (openGLCD)
which can be found here:
https://bitbucket.org/bperrybap/openglcd/wiki/Home

It handles progmem very differently and has no issues with Arduino 1.5.7 and 
the newer versions of gcc.

Righto, and thanks for the pointer to openglcd.
