Questa compilation warnings with -lint?

[jgg]

I was just working on dropping OVM into our build environment with Questa and noticed that when compiled with -lint (our default flags) there are a number of warnings..

The global_configuration_table warning seems to be because the definition is not before some usages in the include order, and the class handle warning is from a few usages of the c-like
if (cls) xxx
rather than
if (cls != null) xx

The enum ones seem a little bit too pedantic if you ask me

Just thought it was worth mentioning if nobody has tried this before.

On further use this seems to be an annoying problem since some warnings appear even when I compile my own modules with -lint, this ones actually:

** Warning: [8] base/ovm_component.sv(2138): Undefined variable: global_configuration_table.
** Warning: [8] base/ovm_component.sv(2149): Undefined variable: global_configuration_table.
** Warning: [8] base/ovm_component.sv(2165): Undefined variable: global_configuration_table.
** Warning: [8] base/ovm_component.sv(2200): Undefined variable: global_configuration_table.

Even though I don't (yet) use includes.. Seems like a strange Questa thing, but it would be nice to see this fixed in future OVM versions. I fixed it in my copy to eliminate the compiler warnings..
