1) Use the autoconf-generated configure script, and the resultingMakefiles (which use libtool and gcc to do the compilation). I usethis myself, but it might be hell to setup correctly. Doesn't workcorrectly in all directories, for instance in the po* directories itis much easier to use the makefile.mingw files.
2) Use the Microsoft compiler, cl and Make, nmake. Say nmake -fmakefile.msc in various directories. These makefiles are maintained byHans Breuer <email@example.com>. They presumably will not generate thesame name DLLs and import libraries as the autoconfiscated libtoolbuild does, nor necesarily use the same named GLib, GTK etc importlibraries as those distributed from the web site mentioned above.
