.B -gstd-include\fI|\fP-gno-std-include
Enable (default) or disable the search of a standard installation
include directory after all other explicit include directories. This
standard include directory is a convenient place to install standard
header files that a Verilog program may include.

.B -gxtypes\fI|\fP-gno-xtypes
Enable (default) or disable support for extended types. Enabling
extended types allows for new types that are supported by Icarus
