To whom it may concern: The common software we write at GM Powertrain is not dependent on the target processor. Therefore, there is no machine specified in the GCC compiler options. However, the target compilers (not GCC) have options to force an enum to be 16 bits (signed). Is there a similar option for GCC? We are using version 3.02. The option "-fshort-enums" will not work as this will force most enums to be 8 bits. Regards, Kevin Baltes Software Build Tools Development Team
