Yes - it happened to me yesterday - hence the impetus for my
report...

I really appreciate your efforts too!

Well, I regularly compile about 250k lines of F90 and C++ code.
Since gfortran 4.3 came out, it has been working pretty well.

Since you do the cygwin builds, you might be interested that there is
another problem with it at link time.  When I use g++ to link programs,
the 3.4.4 libstdc++ wants to use the 3.4.4 libgcc for externals such as
"___w32_sharedptr_terminate" (and friends).  However my build scripts
set up the library paths such that the libgcc.a that is supplied with
gfortran is used instead.  The new libgcc does not have the required
externals, so I get unsatisfieds.  I have to rename the newer libgcc
to fake out the linker, and then all is well.
