I'm sorry to confuse you, but as a matter of fact none of this tricks
is necessary to build GiNaC on windows. I'll elaborate in a moment.

So one need to set PKG_CONFIG_PATH using windows paths, i.e.

Windows version of pkg-config overrides the `prefix' variable with
the actuall installation directory anyway, so this is not necessary.

This is not necessary. compile_ex won't work on Windows anyway. (Hint:
the ginac-excompiler script is Linux specific). And libgw32c already has
dlopen and friends.

Likewise. It does *nothing* useful and confuses the configure script:
configure:24479: checking for dlopen in -ldl
configure:24514: g++ -o conftest.exe -g -O2 -I/mingw/include -I/usr/local/octave-3.0.0/include -I/GnuWin32/include -L/mingw/lib -L/usr/local/octave-3.0.0/lib -L/GnuWin32/lib -L/GnuWin32/bin conftest.cpp -ldl -lgw32c >&5
configure:24520: $? = 0
The configure scripts detects dlopen in libgw32c.dll and enables compile_ex,
which is the WRONG thing.

You don't need pkg-config if you set the compiler and linker flags manually.
Or the other way around: you don't need to set the compiler and linker flags
manually if you use pkg-config.
All science is either physics or stamp collecting.
