Configureation bug on powerpc-ibm-aix4.2.1.0

[Joerg Pietschmann]

Hi,
I got the following error while bootstrapping the egcs snapshot
19990616 on powerpc-ibm-aix4.2.1.0:

t384@neptun:...gcs-19990616>make bootstrap

make: *** [bootstrap] Error 2

The reason is the following line in the Makefile:

# Warning: this fragment is automatically generated
/home/lis5p/t384/gnu/unpack/egcs-19990616/configure[755]:
./../libio/config.shared:  not found.


This looks like a problem with deeper nested multilib directories,
the path should be ./../../libio/config.shared or absolute (or perhaps
./../../power/libio/config.shared?).
Should i suggest that `srcdir' should be transformed into an absolute
path before it is used in the configure.in file?
If you choose to skip this directory as apparently done with soft-float,
keep in mind that there is a powerpc subdir too.

As a sidenote I suspect that also wrong -I directives are generated for
XCXXINCLUDES for deeper nested multilib directories but this does never
show up in any Makefile.
