Bug 32560

I'm not seeing the issue, any ideas what this 64-bit-portability test tests for?

Assign to Brian Paul since he introduced it with one of his commits last week ...

I'm not seeing those warnings here, neither on 32- nor 64-bit systems.  Are you sure your git tree is up to date?

I am 100% sure because I update it normally each day (see: https://build.opensuse.org/package/source_history?package=Mesa&project=home%3Ajobermayr )

Here is complete list of things I build:
https://build.opensuse.org/project/monitor?project=home%3Ajobermayr

Mesa is only "succeeded" because I changed manually the package which is responsible for the actual build error to print only a warning ...

May you can reproduce it with following:

export 'CFLAGS=-fomit-frame-pointer -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables -fasynchronous-unwind-tables -g'

export 'CXXFLAGS=-fomit-frame-pointer -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables -fasynchronous-unwind-tables -g'

It is default on openSUSE distro ...

OK, the key thing was the -DFEATURE_ES1=1 flag which disable glDrawPixels and glBitmap support.  The prototypes in the .h file were skipped.

Fixed with commit c94996f0570c729b9cb2b55329ababb9877fbbea
