Follow-up Comment #8, bug #25713 (project make):

I believe bsd_signal() is detected because the configure script checks
whether the function links, not whether the headers provide a prototype.

The bsd_signal() check itself, as recorded in config.log, is pretty
perfunctory:


configure:7340: checking for bsd_signal
configure:7340: cc -std -o conftest -g   conftest.c  >&5
configure:7340: $? = 0
configure:7340: result: yes


(I see that AC_CHECK_FUNCS() is used for this in configure.in, which does
only check whether a function links.)

Anyway, looking at /usr/include/signal.h (attached), "#define
_XOPEN_SOURCE_EXTENDED" is needed to get the bsd_signal() prototype. That
allows main.c to compile.

But now I remember where the integer-type error came from. It's a knock-on
effect of _X_S_E, causing trouble in the system's own header files:

As originally reported, adding "#define _OSF_SOURCE" does the trick.
