gcc -s

gcc -s

[John Paul Morrison]

I noticed 

i586-cygwin32-gcc -s -o foo.exe foo.c 

produces a corrupt executable that windows NT won't run. 

i586-cygwin32-gcc -o foo.exe foo.c
i586-cygwin32-strip  foo.exe 

produces a working binary.

This is with cygwin32 b17.1 cross compiled on Irix 5.3

This bug has been reported many times on this list.

I spend a few minutes putting together a list of bugs in b17.1 that
I know about, people may find it useful.  See
