I extracted it under cygwin with "tar (GNU tar) 1.13.25"

No. The timestamps seem to be okay.

NTFS on WinXP with SP2

That was the right question!
I modified some files (not only to make them work under cygwin
but some other changes) and guess which header files I changed...
svn_client.h, svn_ra_svn.h, svn_repos.h and svn_version.h
So I found the solution for the problem of the header files being
regenerated: I mustn't change the (source) header files
(or the corresponding .swg files have to be regenerated - as the
make process correctly did).
Unfortunately it doesn't help leaving these header files as they
are to solve my compile problem. I still get the same errors:
[...]
core.c:104: error: syntax error before "int"
core.c:119: error: syntax error before "int"
core.c:138: error: syntax error before "int"
[...]
After doing a 'make extraclean-swig-pl' all .swg files
are being regenerated and the compile is successfull.

Indeed, after switching to swig 1.3.25 everything is alright.

To put it in a nutshell, the .swg files were regenerated because
I changed their source header files, if not changing these header
files I still get the same compiler errors, doing
'make extraclean-swig-pl' before 'make swig-pl' makes it work.
Finally, just a thought about the .swg files: I suppose that it may be
a problem if I changed some (source) header files and after that only
the corresponding .swg files are regenerated as this leads to some
.swg files generated with swig 1.3.24 (if this is the installed version)
and some with swig 1.3.25.
Wouldn't it be better to say "regenerate all .swg files if at least
one is out of date"?
Thank you very much for your help!
