[SDL] Problem with SGE

[John Popplewell]

Hi,

> msvcrt.lib(MSVCRT.dll) : error LNK2005: _exit already defined in 

suggests that the release version of MSVCRT is being used.

> LIBCD.lib(crt0dat.obj)

suggests that the debug version of LIBC (single threaded) is being used.

(1) first of all make sure that all static libraries and DLLs linked to
are either _all release_ or _all debug_ in nature.

(2) all static libraries and DLLs used _must_ link to MSVCRT which
translates, in MSVC++, to:
"Project Settings|C/C++|Category:Code Generation|Use run-time library:
Multithreaded DLL or 
Debug Multithreaded DLL". 

Anything else generates these warnings/errors and can cause various 
run-time problems if you do manage to get it to link with mixed-up 
versions of the RT.

Good Luck,
cheers,
John.
