// MinGW personality wrapper for pkgconf
// This is an executable replacement for the shell scripts /bin/ARCH-pkg-config
// Compile with e.g.
// gcc pkg-config.c -DARCH=x86_64-w64-mingw32 -o pkg-config.exe
// gcc pkg-config.c -DARCH=i686-w64-mingw32 -o pkg-config.exe
// ATTENTION: Do not compile with MinGW-gcc, compile with cygwin gcc!
//
// To test it execute e.g.
// $ ./pkg-config --path zlib
// /usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig/zlib.pc
