Subject: Add our own trivial version of stdarg.h.  This makes our build
X-Git-Tag: v0.9.3~392
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1ae549b892327784141a828f00c68c0b9bc06142;p=thirdparty%2Fipxe.git

Add our own trivial version of stdarg.h.  This makes our build
entirely self-hosted (which avoids problems when building the same
tree on multiple systems - e.g. when you have /home NFS-mounted).

Also saves around 50 bytes in total - not sure why.
