Problem executing m4 (127 error, but it is installed)

[Kizito Porta Balanyà]

Hello,

I'm trying to build MONIT, but with the new version of cygwin, I need m4.

I have installed it, but when running it, I get a 127 error:

$cd /usr/bin
$ m4
$ echo $?
127

To test that really m4 exists, I try m5:
$m5
-bash: m5: command not found

It is a little strange, Antivirus is configured to no scan the cygwin unit.

I'm usuing, CYGWIN_NT-6.3 MYHOSTNAME 2.0.1(0.287/5/3) 2015-04-30 18:15
x86_64 Cygwin

Do you have any idea ? Can you help me?

Thanks a lot for your time
