[I am using gcc v4.3.3]

While building xserver v1.9.0 (with xproto v7.0.17) on Solaris 10 x86/sparc, I face below two issues:

Issue #1 (observed only on Solaris 10 x86):

<<<<>>>>

The below patch to Xext/panoramiX.c fixes the issue:

However, I am not sure if the above is the right place to fix. Probably, xproto is:
