Is there a decent IDE for gnu fortran with gcc ?  I tried Simply Fortran

the Xth call to a subroutine and Simply Fortran does not support that.
I have 5,000 subroutines (800k lines of F77), 300 common blocks, and
500K lines of C++ in over 10,000 files in my calculation engine.
Managing that without an IDE is challenging.

 Eclipse might.  To be honest I just use gdb for debugging outside of an
IDE.  Used to love TotalView until it got too expensive (and I don't know
if it is even available for Windows).
 

My Hollerith is gone.  My structures and unions are reduced. The code
actually converts to C++ fairly well until you get to the formats.

 The older f2c used to do all the formatted I/O with a runtime library...
much the way most fortran implementations do.

I used gdb to debug x-windows and xview apps back in the early 1990s. The command line version kinda sucked.
Yeah, the formatted i/o from f2c really sucks.  It converts the formats and writes into a series of executable statements using static memory images.  I have seen one write statement translated into 30+ new statements.  This is why I convert write statements by hand.
The real problem is that we have a Fortran interpreter embedded in our software.  It uses a very primitive byte stream written in Fortran. However, it cheats on Formats and pipes them directly into a Fortran write statement.
