Bug #4031
closedconfigure: $NM is empty, causing "command not found"
Description
=begin
Running autoconf (2.61), and then ./configure result in an error (ignored):
"./configure: line 39432: conftest.o: command not found"
This come from nobu's commit from yesterday
29706: (configure.in (rb_cv_export_prefix): check for prefixed underscore of exported symbols)
but seems to be a deeper issue, because the error is caused by $NM not being defined or empty at that time.
I searched around, and apparently the 'fi' at line 5324 of the generated configure does not match any 'if', but I could not look further as a 41688-lines generated file is hard to read.
Maybe this issue is from autoconf, I do not see any reason why it would not find my nm at /usr/bin/nm.
I join the configure executable generated.

This issue was solved with changeset r29710.
Benoit, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.

Now I see:
configure: WARNING: Cache variable rb_cv_export_prefix contains a newline.
Is that expected?

I don't see it, on both of darwin and linux.
What's the result of the following command?
$ grep -A1 export_prefix config.cache
Try with removing the rb_cv_export_prefix line from config.cache file, or removing the cache file itself.

=begin
$ grep -A1 export_prefix config.cache
I do not have any config.cache
However, config.log match (and is the only, except configure and configure.in):
configure:40468: WARNING: Cache variable rb_cv_export_prefix contains a newline.
configure:40571: creating ./config.status
configure:41710: WARNING: Cache variable rb_cv_export_prefix contains a newline.
ac_cv_build=x86_64-apple-darwin10.4.0
I deleted the config.status, but nothing changed, even when restarting from zero (rm, autoconf, ./configure)
I still have it at every ./configure
The value of rb_cv_export_prefix seems to be:
_
_
(two underscores with a \n between)
