Dear Sirs,

I recently downloaded Cygwin B20 = (beta 20.1)=20 from your web site

and I thank = you very much=20 for your phantastic work.

The downloaded setup file is full.exe version=20 2.02.001.

I installed the downloaded software and everything=20 runs

well. Yesterday, I tried to compile the file ivp.c = attached=20 to

this mail = message.

gcc ivp.c produces a ./a.exe file. = When I try to=20 run it, bash

answers "permission = denied". When I=20 try to run it from NT's

command shell cmd.exe, cmd.exe = answers "not=20 a NT application"

in a modal dialog and then prints = "access=20 denied" on its own

window.

g++ ivp.c (same file) takes a lot to = compile. It=20 seems that the assembler

is responsible for that (as.exe = takes a lot of=20 CPU time).

After a minute or more g++ = terminates with the=20 following message.

C:\TEMP\cc6JXrCu.s: Assembler=20 messages:
C:\TEMP\cc6JXrCu.s:485: Fatal error: Cannot write to output = file.

When you modify the source code by=20 replacing

#define dt ((double) = 1.0e-8)

with

#define dt ((double) = 0.05)

everything works fine. It seems the=20 compiler.

Yours sincerely, Roberto
