>Description:

On IRIX, certain C library functions are omitted from C++ headers unless a 
particular flag is passed to the C++ compiler.

Despite having CXXFLAGS+=-LANG:exceptions=OFF:libc_in_namespace_std=OFF in the 
devel/pcre Makefile and added to my CXXFLAGS environment variable (which has 
propagated through to pcre's top-level Makefile), I get the error:

*** Error code 1

... where you'll notice that something (libtool? wrapper.sh?) has stripped the 
additional CXXFLAGS - rendering the code un-buildable.
>How-To-Repeat:

'cd devel/pcre && bmake' on IRIX
>Fix:

If I manually run the command specified by wrapper.sh with the correct flags 
added, then the file if compiled successfully.  However, if I then return to 
the top-level and "bmake" again, the build system attempts to rebuild the code 
again without the additional flag, and again fails :(
