spec file and -arch

[Stefan Leichter]

Hi,

when i look into msvcr100.spec file i find lots of different parameters for the 
switch (?) -arch . So fare i have seen: arm, i386, win32, win64 and x86_64 .

To me it is not clear what is the difference between win64 and x86_64. The same 
for i386 and win32. What are is the criteria to choose the first or the second? 
If it makes a difference do i have to distinguish between arm and ... ?

Does -i386 and -arch=i386 mean the same?

Thank you for enlightening me
Stefan

win32 includes all 32-bit platforms
win64 includes all 64-bit platforms

if is implemented in x86 assembler win32 would not be the best choice.

i suggest you should use make_specfiles in tools/
