Subject: autoconf: Report the compiler options in the summary
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=16a07fb5569a7e4d471a389f292a8b245fc12cba;p=mesa.git

autoconf: Report the compiler options in the summary

Report the compiler flags and macros that will be used in the build.
This just provides a quick way to see what configure has silently been
doing.
