- Check for undefined/null regex flags (because...)
- Make it throw a typeerror instead of syntax error on non-global
- Generalize JS error messages for these checks.
This should do it for all the commits to files I changed, but while I'm in here I could probably go ahead and turn ALL the singular if defined statements into ifdef statements by using grep/find on the tree. On the other hand, perhaps we should do that as a separate issue so that this doesn't become a case of scope creep.
This fix is a bit ugly and may need to be changed later if we switch a new GCC version, but the fact is that we use an architecture-specific path for GCC libraries on Solaris, so knowing the right prefix for GCC would only help so much, because it would still need to decide between ${gccdir}/lib and ${gccdir}/lib/amd64. The MOZ_FIX_LINK_PATHS variable puts the search paths into the right order without the need for me to use elfedit on the binaries afterwards.

Setting this up turned out to be easier than I thought it would be. All I had to do was apply these instructions in reverse and add the following to my .mozconfig file:
CC="gcc -m64"
CXX="g++ -m64"
AS="gas --64"
ac_add_options --target=x86_64-pc-solaris2.11
export PKG_CONFIG_PATH=/usr/lib/amd64/pkgconfig
ac_add_options --libdir=/usr/lib/amd64
ac_add_options --x-libraries=/usr/lib/amd64
Most of these changes were fairly trivial, just requiring me to make a few of the changes I made earlier conditional on a 32-bit build. The biggest challenge was figuring out why the JavaScript engine triggered a segfault everytime it tried to allocate memory. But this patch fixes it:

Turns out that Solaris on AMD64 handles memory management in a fairly unusual way with a segmented memory model, but it's not that different from what we see on other 64-bit processors. In fact, I saw a SPARC crash for a similar reason, and noticed that it looked just like mine except the numbers in the first segment were reversed. Having played around with hex editors before, I had a feeling I might be dealing with a little-endian version of a big-endian problem, but I didn't expect that knowledge to actually yield an easy solution.

As far as I can tell, this was the last barrier to an AMD64 Solaris build of Pale Moon.
