## 4. Notes for building XFree86 on SVR4

1. If you are using gcc with SVR4, we highly recommend that you use gcc-2.4.5 (or a later stable release). Version 2.6.0 has some problems on i386 platforms and is not recommended.
2. It is recommended that you increase the `UFSNINODE` (for a UFS filesystem) and/or the `S5NINODE` (for an S5 filesystem) kernel parameter to about 650 before attempting to build the distribution. See the "Notes for running XFree86 on SVR4" section for some other parameters you may want to change.
3. The `BOOTSTRAPCFLAGS` required are:

   > For Unixware: "`-DUSL`" For NCR: "`-DNCR`" For other SVR4: "`-DSVR4 -Di386`"
