Re: Help cross compiling for MingW32 standalone executables.
You are right, I am using the -lm flag. However, you are wrong in that I am
not using an "older" version of cygwin. I just ran "setup" and all my
development packages are listed as "keep", meaning
they are the most current stable versions. For example:
gcc is 3.2-3
gcc-mingw is 20020817-5
I've checked and my build does not like in cygwin1.dll if I edit the
Makefile's by hand to remove the -lm flag. The problem is the
"AC_CHECK_LIB(m,sqrt)" autoconf macro always report -lm exists and is needed
for the sqrt function when the host target is i686-pc-mingw32. So anybody
who tries to reproduce my build will have the same problem.
