/* Extension remappings.
|
|
|
|
These remappings cause the insertion of shims when a VM being compiled
|
|
includes this declaration module. The shims are not wanted when compiling
|
|
the extension module itself.
|
|
|
|
|
|
Implementation notes:
|
|
|
|
1. When the extensions are being compiled, the module includes the
|
|
"sim_serial.h" file, which includes the "sim_rs232.h" file. Therefore,
|
|
we do not want to include the latter file a second time and so exclude
|
|
it when compiling the extensions module.
