[gambit-list] gsc gets a linker error with -exe

Hi, I have a scheme program I'm trying to compile with Gambit-C in MinGW/MSYS under Windows. If I do

gsc -exe "filename"

the c file is output and gcc compiles fine-until it gets an error in the linker stage:( after successfully compiling DansScheme1.o and DansScheme1_.o and attempting to link them) C:...lib/libgambc.a(os_base.o):os_base.c:(.text+0x737):undefined reference to 'gai_strerrorA'

If I just compile with gsc -c "filename" it puts out a .c file no problem. What should I be looking for? If you need more details let me know. This is version 4.7.0 using Windows Vista with the prebuilt binaries. Any help would be much appreciated.Thanks, Dan
