Subject:	Compiled executables requiring admin rights - different results between MinGW host type
Date:	Tue, 11 Mar 2014 11:50:37 -0700
MIME-Version:	1.0

Hi, I'm looking at a very simple 32-line c file, source is available here 
https://github.com/JuliaLang/julia/blob/master/contrib/stringpatch.c

I'm seeing unpredictable results w.r.t. the compiled executable requiring 
admin rights to run, depending which host compiler is used.

Under 32 bit Cygwin:
gcc -o stringpatch-cyg stringpatch.c   # requires admin rights
i686-pc-mingw32-gcc -o stringpatch-pc-32 stringpatch.c   # requires admin 
rights
i686-w64-mingw32-gcc -o stringpatch-w64-32 stringpatch.c   # requires admin 
rights
x86_64-w64-mingw32-gcc -o stringpatch-w64-64 stringpatch.c   # does not 
require admin rights

Under 64 bit Cygwin:
gcc -o stringpatch-cyg stringpatch.c   # does not require admin rights
i686-pc-mingw32-gcc -o stringpatch-pc-32 stringpatch.c   # requires admin 
rights
i686-w64-mingw32-gcc -o stringpatch-w64-32 stringpatch.c   # requires admin 
rights
x86_64-w64-mingw32-gcc -o stringpatch-w64-64 stringpatch.c   # does not 
require admin rights

What is the explanation for this discrepancy? Is this expected behavior? Is 
there an easy way to prevent any of the compiled executables from requiring 
admin rights?

All the compilers are version 4.8.2, with the exception of 
i686-pc-mingw32-gcc which is version 4.7.3 in both 32 and 64 bit. Cygcheck 
contents for both installations are posted here 
https://gist.github.com/9492379. If providing any additional info would be 
useful, please let me know.

Thanks,
Tony
