This is my theory:
It could be that Ipopt has is compiled with -MT, but the f2c lib
without. Then Ipopt requires libcmt.lib, while the vcf2c.lib depends on
libc.lib. Now, by forbidding libc.lib, we made Ipopt happy, but
vcf2c.lib unhappy.
Can you check (and maybe recompile) vcf2c.lib to make sure that the -MT
flag was used when compiling? (Adding -MT to the CFLAGS in makefile.vc
should suffice.)

I am not building with Visual Studio, so I have not tried this.

Good luck,
Stefan
