No. However, compilation by itself is a mechanical task which performs no

Sure. If you link an executable against Oracle's client libraries to talk to
their database, that executable includes proprietary code which would need to
be appropriately licensed.

The GPL provides an exception for their compiler runtime library which permits this:
Most or almost all other compilers also explicitly permit the use of the associated
compiler runtime libraries with software under arbitrary licenses. End-users rarely
encounter this because most platforms already ship with working versions of the
compiler runtime and standard C/C++ libraries, and programs use dynamic linking to pull
those in rather than needing to statically link them into the executable. 
: Folks using Windows probably encounter more dialogs about installing a flavor of the
"Microsoft Visual C/C++ redistributable libraries" than all other platforms combined.
