Hello there,

I just tried to compile X11R6.8.1 with the most excellent Intel C
8.1 compiler, on a Linux Fedora Core 3 box. The compiler said

glxcmds.c(1508): remark #592: variable "req" is used before its value is set

The source code is in file

./lib/GL/glx/glxcmds.c

The source code is

    if ( (priv->majorVersion > 1) || (priv->minorVersion >= 3) ) {
    xGLXQueryContextReq * req;

    req->reqType = opcode;
    req->glxCode = X_GLXQueryContext;
    req->context = (unsigned int)(ctx->xid);
    }

Clearly, the compiler is correct. Suggest init req before first use.
