Subject: glcpp: Actually support #ifdef and #ifndef.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=77260fc0a04c72c98389adeb7244467e10ef2979;p=mesa.git

glcpp: Actually support #ifdef and #ifndef.

Strangely, the lexer never created these tokens, even though the parser
already had code to handle them.
