Summary: Fortran Hello World program fails to compile!

Initial Comment:
OS Win2000
gcc version 3.4.0 (mingw special)
GNU ld version 2.15.90 20040222
MinGW 3.1.0-1
Build environment MSYS


The following Fortran program fails to link:

      PROGRAM F77TEST

      PRINT *, 'Hello, FORTRAN program working.'

      END

The error encountered is:

prompt>g77 f77test.f 
C:/Mingw/bin/../lib/gcc/mingw32/3.4.0/../../../libg2c.a
(endfile.o)(.text+0xc5):endfile.c: undefined reference to 
`ftruncate'

Note the following entry in the changelog file which may 
be pertinent to this error:

2004-03-22  Danny Smith  
<dan...@us...>

	PR target/14291
	* gcov-io.h (gcov_truncate): Define ftruncate 
as _chsize for
	__MINGW32__.


and that ftruncate also occurs in endfile.c, as noted in 
the error message above. This problem affects not only 
Fortran main programs but also affect any program linked 
with Fortran code (certain in my own case: Ada code 
calling a Fortran library).
