| Description: force pentium optimized compilation
| Replaces gcc, cc, and g++ with scripts that build pentium optimized code.
| (Other processors can be optimized for as well.)

| By default, after installing this package, the compilers will behave
| normally. However, if the environment variable DEBIAN_BUILDARCH=pentium
| is set, they will enter pentium optimized compile mode.
