[Ace-users] [ace-bugs] [ACE Autoconf setup]: [ACE_HAS_MUTEX_TIMEOUTS ./configure error under LINUX]

[korf.peter at arcor.de]

Hi,
ACE VERSION: 5.5.9

HOST MACHINE and OPERATING SYSTEM:
Linux 2.6.18.8-0.3-default #1 SMP
x86_64 x86_64 x86_64 GNU/Linux
SuSE 10.2

COMPILER NAME AND VERSION (AND PATCHLEVEL):
gcc (GCC) 4.1.2 20061115 (prerelease) (SUSE Linux)

SYNOPSIS:
ACE_HAS_MUTEX_TIMEOUTS will not defined using the ./configure script due a compiling error.

DESCRIPTION:
The function in the ./configure script which checks for ACE_HAS_MUTEX_TIMEOUTS fails because 
of (part of config.log): 
...
configure:100395: checking for mutex timeouts
configure:100602: g++ -o conftest -g -O2 -pthread -pipe   conftest.cpp -lrt -ldl  >&5
conftest.cpp: In function 'int main()':
conftest.cpp:248: error: 'exit' was not declared in this scope
conftest.cpp:254: error: 'exit' was not declared in this scope
conftest.cpp:260: error: 'exit' was not declared in this scope
configure:100605: $? = 1
configure: program exited with status 1
configure: failed program was:
....
exit() is defined in header file <stdlib.h>, but this is missing in conftest.cpp.
After adding this header file to the test program, the check is OK. 

REPEAT BY:
run ../configure under linux

IMPORTANT NOTES:
This is only tested on one system under one operating system!

(Don't forget to run autoheader and autoconf after applying the patches)

Thanks for developing and maintaing ACE,
