Subject Re: [porting] PPC Linux and z/OS update
Date Fri, 02 Nov 2007 02:30:41 GMT
To build on z/OS, do we need also to convert build script such as build.xmland
defines.mk etc. into z/OS specific encoding - EBCDIC?

If that's the case, do we need to maintain a separate build script set for
Whether these z/OS specific build scripts readable on other platform?
