There's a new MAWK update on freshmeat, dated 13 Jul 2009.
However, I ran into an error while building it.
gcc -c -DXTSTRINGDEFINES -g -O2 -W -Wall -Wbad-function-cast -Wcast- align -Wcast-qual -Wmissing-declarations -Wmissing-prototypes -Wnested- externs -Wpointer-arith -Wshadow -Wstrict-prototypes -Wundef matherr.c matherr.c:71:21: error: siginfo.h: No such file or directory matherr.c: In function 'matherr': matherr.c:156: warning: unused parameter 'e' make: *** [matherr.o] Error 1
This is in Mac OS X 10.4. The man page says, "The matherr() function is deprecated. Use the floating-point enivronment routines instead. Prototypes for those functions can be found in the header file fenv.h."
Anyone have a suggestion on how to get a working mawk in this situation? Is there some was to install what matherr needs without breaking anything else?

As far as I understand the error text, gcc does not complain about the matherr() function but about the missing file siginfo.h. But I do not know where to get this for Mac OS X :-( On my openSUSE box, it seems to belong to glibc-devel package.
Mawk was written by Mike Brennan. There has been no maintainer for some time. I have adopted it, starting with fixes from the Debian package, and resolving issues which the package maintainer did not respond to.

That should only have been including siginfo.h if the configure script found sigaction_t and siginfo.h - and defines SV_SIGINFO (see config.h). However, my snapshot of 10.4 headers doesn't have siginfo.h (I don't have an OSX to test directly on). But I see that sys/signal.h defines SV_SIGINFO - so the problem is that the configure script from long ago chose a symbol that happens to be defined in OSX's headers.
