Possible bug in build-system

From: Christian Fischer <Christian.Fischer_at_HOOD-Group.com>

Hello all!

I tried to co and compile the current subversion rev35640.
While running autogen.sh I discovered an error regarding a missing file:

WARNING: "rep-cache-db.sql.h" header not found, file
subversion/libsvn_fs_fs/rep-cache.c

As autogen.sh also ./configure does not fail explicitly. But make does.
So I tried a earlier revision and isolated revision 35542 (42..hrhr) as
first version throwing the error.

BUT: You will never discover the bug, if you are updating your wc from
an earlier version (and run autogen.sh before) - here is why:
In autogen.sh those headerfile will be updated if the rep-cache-db.sql
file has changed.
Revisions =<35541 are also generating these header file - or simply
running always the responsible python scripts. (see below)

I added "if not existent" and now it works like a charm!

Sincerely
Christian Fischer
