llvm dev - Sep 2004 - [LLVMdev] SlowOperationInformer.cpp:55: error: `SIGALRM' undeclared (first use this functi

Hi

I'm compiling: /usr/local/src/llvm/lib/Support/SlowOperationInformer.cpp on 
MinGW. However, it stops complaining about that SIGALRM is undeclared:
--------------------------
@ /usr/local/build/llvm/mklib --tag=disable-shared --silent --tag=CXX 
--mode=compile g++ -c -I/usr/local/build/llvm/lib/Support 
-I/usr/local/src/llvm/lib/Support -I/usr/local/build/llvm/include 
-I/usr/local/src/llvm/include -I../../include -I/usr/local/src/llvm/include 
-D__MINGW -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -Wall -W -Wwrite-strings 
-Wno-unused -g -D_DEBUG 
/usr/local/src/llvm/lib/Support/SlowOperationInformer.cpp -o 
/usr/local/build/llvm/lib/Support/Debug/SlowOperationInformer.lo
C:/MinGW/msys/local/src/llvm/lib/Support/SlowOperationInformer.cpp: In
   constructor `llvm::SlowOperationInformer::SlowOperationInformer(const
   std::string&)':
C:/MinGW/msys/local/src/llvm/lib/Support/SlowOperationInformer.cpp:55: 
error: `
   SIGALRM' undeclared (first use this function)
--------------------------

On mingw the signal value SIGALRM isn't declared in <signal.h>.

I can't figure out what to do next. Any suggestions?

Henrik

Is there an alarm() syscall on MinGW?  And if so, what signal does it 
send (according to the MinGW docs)?

Ultimately, this is another function that needs to go into lib/System. An 
alternate approach is to fork a thread, sleep, and when the thread wakes up, 
"ring the alarm".
