Hello,
I noticed that the "break" called in a parameter to
AC_LINK_IFELSE skips the command
rm conftest conftest.$ac_objext ...
This means that the files are left uncleaned.
The patch attached to this mail exposes the problem.
There are two ways to fix the problem:
1) Add a "rm" to AC_SEARCH_LIBS
2) Fix the macro AC_LINK_IFELSE so that it cleans up before it executes
the commands given as parameters.
Variant 2) seems cleaner. If we decide for it, we also have to fix
a dozen of similar macros in autoconf/general.m4.
Which variant would the reders here prefer?
Have a nice day,
Stepan Kasal
