To all,
I have been facing a problem on Windows/MinGW with autoconf. The
configure generated script crashes when called via "config.status
--recheck":
../src/configure: config.log: Permission denied
The reason is that config.log cannot be truncated by configure because
config.status already opened it (and Windows forbids truncating an open
file). Here is the fix (tested on Windows/MinGW).
Best regards,
Eric
