This option just triggers gcc to use other lib and include paths, as they are defined in the specs. So it seems gnat doesn't use the specs when linking. Note that it works quite well with include paths when compiling the source? I will provide a workaround in the upcoming release of cygwin gcc-3.4.4, in addition to -mno-cygwin another flag is needed then: --RTS=no-cygwin This will cause gnat to pick up the right runtime if the gcc-mingw-ada package is correctly installed. Then there is a new subdirectory in i686-pc-cygwin/3.4.4 named no-cygwin with symlinks to the mingw runtime: /---3.4.4 | /---adainclude | /---adalib | /---no-cygwin | +---adainclude | +---adalib $ gcc -v -c --RTS=no-cygwin -mno-cygwin hello_a.adb Reading specs from /usr/lib/gcc/i686-pc-mingw32/3.4.4/specs Configured with: /gcc/gcc-3.4.4/gcc-3.4.4-1/configure --verbose --prefix=/usr --exec-prefix=/usr --sysconfdir=/etc --libdir=/usr/lib --libexecdir=/usr/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-languages=c,ada,c++,d,f77,java,objc --enable-nls --without-included-gettext --enable-version-specific-runtime-libs --without-x --enable-libgcj --disable-java-awt --with-system-zlib --enable-interpreter --disable-libgcj-debug --enable-threads=posix --enable-java-gc=boehm --disable-win32-registry --enable-sjlj-exceptions --enable-hash-synchronization --enable-libstdcxx-debug : (reconfigured) Thread model: posix gcc version 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125) /usr/lib/gcc/i686-pc-mingw32/3.4.4/gnat1.exe -quiet -dumpbase hello_a.adb -mno-cygwin -mtune=pentiumpro -fRTS=no-cygwin hello_a.adb -o /tmp/ccqn0PMb.s /usr/lib/gcc/i686-pc-mingw32/3.4.4/../../../../i686-pc-mingw32/bin/as.exe -o hello_a.o /tmp/ccqn0PMb.s $ gnatbind -v -aO./ --RTS=no-cygwin -I- -x hello_a.ali GNATBIND 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125) Copyright 1995-2004 Free Software Foundation, Inc.

I'll try to find a way to integrate this in to the binary to make it work as one expect it to work. Gerrit -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20530
