Re: compiling C library under mingw

I did a little search and I found that probably there is a library (dll or lib ???) that contains all these references. I could specify it by using -L/C/path/to/libraries -libraryname as an option to the second gcc command, but I have no idea what the library is and where to find it (I used -L/C/PostgreSQL/9.0/lib -lpostgres -lpq, but it didn't work).
All those references are declared as extern in postgres source code.
Does anyone know what the library is?

I have a library that compiles fine under linux.
But when I try to compile it under mingw on windows 7 I get the following errors.gcc.exe -c -O2 -I/C/PostgreSQL/9.0/include/server -I/C/PostgreSQL/9.0/include/server/utils -I/C/PostgreSQL/9.0/include/server/access -I/C/PostgreSQL/9.0/include/server/port/win32 -I/C/PostgreSQL/9.0/include -MMD -MP -MF build/Release/MinGW-Windows/mylib.o.d -o build/Release/MinGW-Windows/mylib.o mylib.c
The previous command is successful and produces .o files (only some warnings here like: warning: 'pg_finfo_mytype_in' redeclared without dllimport attribute: previous dllimport ignored).
The following though gives errors.gcc.exe -shared -o dist/Release/MinGW-Windows/libMyLib.dll build/Release/MinGW-Windows/mylib.o
