   ok. after i lobotomized the configure script in libf2c, libf2c was
   built except for dtime_.c and etime_.c

   i managed to build brain-dead versions of them, so that i have now
   a functioning cross-compiler, that i have already tested with some
   fortran sources: it's all right (the .exe's work, giving correct
   answers), except for dtime/etime

   the warnings are directed to the header file that tries to declare
   the union with HighPart and LowPart

   here it is the relevant output of make, when i repristinated the
   original code in etime
