MORE INFORMATION
GCC assemblies have the .comm directive and the .lcomm directive. These directives are used to define global symbols and local symbols. In an Interix environment, these symbols are not always aligned with the 16-byte boundaries. However, if you use a custom compiler to compile the GCC assemblies that are not aligned with the 16-byte boundaries, any optimization that is used by the custom compiler will fail.

Windows Services for UNIX 3.5 includes the Interix subsystem technology. The GCC is a compiler in the Interix subsystem technology. For more information about the Interix subsystem technology, visit the following Microsoft Web site:
