I imported a copy of libcurl 7.37.0 into a repository for the project I
am working on. The "svn log" message simply shows how I modified the
file in revision 42 of that repository. The directory name in the
prompt for my previous response is too terse; I hacked it a bit too much
to hide my project name. It is actually the project name followed by
"curl-7.37.0\winbuild", so I was showing the difference in
"/project/\curl-7.37.0\winbuild\Makefile.vc".

What the log says is: after revision 41, the line "@SET
RTLIBCFG=$(MODE)" was added after the line "@SET MACHINE=$(MACHINE)" in
the file "winbuild\Makefile.vc". This is the change you would need to
make, using any text editor. If you are not using a version control
system (OK if you are just experimenting) then you wouldn't be comparing
revisions. You would simply be comparing the released version of
libcurl 7.34.0 with your modified version.

To repeat exactly what I've done, you would need to create a repository,
check out a working copy, import the libcurl source code into the
working copy, commit the original form of the libcurl source code from
the working copy to the repository, modify Makefile.vc as I showed,
commit the changed file, and then run the comparison vs. the revision
(whatever its number) just prior to the commit.

This is an awful lot of work if you are not yet familiar with a source
code control system. Knowing how to use one is a good thing (ever
wonder "what did that code look like before???"), but if all you want to
do is link your program, just add the one line to Makefile.vc in your
project directory tree, rebuild libcurl, and let us know how it works.

P.S. I can't help you with specific questions about TortoiseSVN; I've
never used it. Instead I use the command-line version of Subversion
because it works the same way on Linux too. You can download a free
book on the command-line version of Subversion (includes information on
how to set up and manage repositories) at http://svnbook.red-bean.com/.
There is probably online documentation for TortoiseSVN that is equally
useful. I know that there are E-mail support groups for Subversion and
TortoiseSVN.
