#includes not being processed across network (revised)

To: cygwin at cygwin dot com
Subject: #includes not being processed across network (revised)
From: M4um at aol dot com
Date: Wed, 3 Jan 2001 14:10:35 EST
This is a resubmission.  I've completely revised my development platform but 
still have a problem getting gcc/cpp to properly process #includes across a 
network.  

The -Idirectory and associated logic for finding the correct header file from 
a series of search paths is working properly (using output from -dM, 
-save-temps and -H compiler-switches), but once the header file is identified 
it is not being processed.  To test this I created a header file with "#error 
Here Is the Error" as its first line in the Windows #include path and it 
correctly errored off.  Moving the header file to Unix, the compiler found 
the file but the #error was not tripped.  In both cases the source code and 
makefile and all scripts, etc., were resident under Windows.

A related problem: If I move the source code (the .c file) to the UNIX box 
the same problem is observed with the added confusion that the .i (output 
from -dM and -H) shows only the first line -- for example, '# 1 "./dcheck.c"' 
-- and nothing else!   In the previous example it contains processing of all 
header files, #defines, etc., as it should.

The Unix file server is VisionFS ("VSFU") and I am running the most recent 
bash, gcc, etc., under Win98 (FAT32)  The server and network have been check 
out and appear to be working "hot, fast and normal".  I've tried to recreate 
the problem "by hand" by invoking sh.exe (not bash) directly, cd'ing over to 
Unix and then doing several instances of "less" on a file in parallel.  The 
system was able to recognize and warn of locked files when I tried to do 
multiple editing sessions of a single UNIX file with vi; all permissions are 
agreeable on both sides of the problem.

Anyone out there have ANY ideas?
