You could also got to the project properties to add curl as a used
library. Dev C++ will do the job of adding -lcurl to gcc for you.

Thanks for your answer :) I know now how do this, but it's not too
comfortable:
gcc -DCURL_STATICLIB -c -g -Icurl/include simple.c
gcc -o simple.exe simple.o -Lcurl/lib -lcurl -lws2_32 -lwinmm
