[LLVMdev] SlowOperationInformer.cpp:55: error: `SIGALRM' undeclared (first use this functi

[Henrik Bach]

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
