I need to use a library supplied by someone else:  libjpeg.lib.  This is a
plain C library.  I do not have the source code.  I do have the header *.h
files.   When I run dumpbin on the libjpeg.lib, it contains symbols (entry
points) like:  

 jpeg_read_header

I'm trying to link my program with this library.  My program is in Visual
C++.  The link fails with link-time errors such as:

 unable to find function _cdecl_jpeg_read_header(int, char*) [more mangling
stuff]

Apparently, at compile time my compiler is mangling the library function
names (from the library header files) to include the parameter types.    

To fix this, I presume, I need to put some instructions into the library's
header files that say "Treat these as normal C functions without mangling".  

Any suggestions on how to make the link successful?  Thanks in advance for
any help.
