This is achieved by adding the -Wno-unused-function flag to the compiler.
The warnings are suppressed to avoid confusion for users new to dwm.
Removing the static declaration from the header files works too, but adds
unnecessary data into the compiled object.
Text from original patch:
Using pango markup for status text
Use a single font. Removed some code utf8 code from drw.
Created for pango 1.44. Older versions might not have getter
for font height, ascent + descent can be used instead.
All texts are rendered with pango but only status is with
markup. Increased stext size (in case a lot of markup is used).
MIN/MAX is already defined (didn't redefine them).
