[CMake] unnecessary linker options when compiling executables with mingw/gcc

[Werner Smekal]

Hi,

recently I found out (make VERBOSE=1) that when an executable is 
compiled with MinGW Makefiles some linker options are in the command 
line, which should be in my opinion only necessary for libraries:

-Wl,--out-implib,libtest.dll.a 
-Wl,--major-image-version,0,--minor-image-version,0

I could reproduce this options with a simple test case (files attached). 
Compiling this project gives (MinGW Makefiles):

Linking C executable test.exe
C:\DevZone\cmake-2.6.2-win32-x86\bin\cmake.exe -E cmake_link_script 
CMakeFiles\test.dir\link.txt --verbose=1
C:\DevZone\MinGW-3.4.5\bin\gcc.exe     CMakeFiles\test.dir\test.c.obj 
-o test.exe -Wl,--out-implib,libtest.dll.a 
-Wl,--major-image-version,0,--minor-image-version,0

It doesn't seem to have any implications, apart maybe from this message: 
 http://www.mail-archive.com/cmake@cmake.org/msg15862.html

Any ideas?

Werner

project(test C)

add_executable(test test.c)int main()
{ return 0; }
