Q149510: BUG: Environment Compiler Options Incorrectly Take Precedence

Product(s): Microsoft Fortran Compiler
Version(s): 4.0

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Fortran PowerStation for Windows 95 and Windows NT, version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Compiler options set with the FL32 environment variable incorrectly take
precedence over like compiler options set either in the Developer Studio
workbench or at the MS-DOS command-line prompt.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. We are researching this problem and will post new
information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION
================

The correct compiler option precedence should be that any like compiler options
specified in the Developer Studio workbench or those used on the MS- DOS
command-line prompt take precedence over similar compiler options set in the
FL32 environment variable.

Steps to Reproduce Problem
--------------------------

1. Set the FL32 environment variable to the /G3 compiler option. At an MS-DOS
  command prompt type:

  " SET FL32=/G3." (without the quotation marks)

2. Compile the sample code code provided using the /G4 compiler option. At the
  same MS-DOS command-line prompt, type:

  " FL32 /G4 test.for." (without the quotation marks)

Note that the compiler discards the /G4 option using the /G3 option instead and
displays the following warning message:

  Command line warning D2005: flag /G4 conflicts with earlier flag.
  Flag ignored.

Sample Code
-----------

  C Compile options needed: none
        print *, 'hello, world'
        end
