758732 - configure sometimes fails with "rm: cannot lstat `conftest.exe': Permission denied" followed by "C++ compiler cannot create executables"

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

+++ This bug was initially created as a clone of Bug #545015 +++

The current delay of 1 is not enough.  As Ehsan has suggested, I'm using timeout of 2 a long time as a local path.  When I sometimes forget to apply it, I get the conftest.exe permission denied error.

Proposing to raise the timeout.

I suggest we just assume that VC++ can create executables and avoid doing this test altogether on Windows, instead of making configure two seconds slower than necessary--especially considering that configure is already ungodly slow on Windows without any sleeping.

What could *possibly* go wrong?  :-)

This check is done by one of the autoconfigure macros (AC_LANG_C or whatever they call it) so we can't skip that particular check quite easily.

And by autoconfigure, I obviously mean autoconf!

It is possible to override bits of the built-in autoconf macros, m4 is pretty flexible.
