Using cygwin 1.17-1, if I try to link any Fortran program with -lm I get the
error
/usr/lib/gcc-lib/i686-pc-cygwin/2.95.2-6/../../../../i686-pc-cygwin/lib/libm
.a(libcmain.o)(.text+0x7f): undefined reference to `WinMain@16'
collect2: ld returned 1 exit status
Now libm.a is a symbolic link to libcygwin.a. I believe the root cause is
linking libcygwin.a before libg2c.a since for any Fortran program I see
g77 foo.f OK
g77 foo.f -lm FAIL
g77 foo.f -lg2c -lm OK
g77 foo.f -lcygwin FAIL
g77 foo.f -lg2c -lcygwin OK
Now the obvious solution is to not use -lm, but then I have to edit
Makefiles (or even worse - hack Dejagnu so I can run the g77 testsuite).
Once upon a time the cygwin libm.a was an empty archive. Can we revert to
this?
