Comment (by kcrisman):

 Sorry, the "second" thing is already in there, so that we use the Sage
 include and lib directories.  I am more or less suggesting that we add
 {{{
 #!diff
 + if BUILD_GLPK:
 +-    glpk = Extension('glpk', libraries = ['glpk'],
 ++    glpk = Extension('glpk', libraries = libraries+['glpk', 'gmp', 'z'],
 +         include_dirs = [ GLPK_INC_DIR ],
 +-        library_dirs = [ GLPK_LIB_DIR ],
 ++        library_dirs = libdirs + [ GLPK_LIB_DIR ],
 +         sources = ['C/glpk.c'] )
 +     extmods += [glpk];
 +
 }}}
 back in the patch file, or at least I think so, at least if `__CYGWIN__`
 is defined.
