Note that I'm renaming the _remaining_ STR*s and not all references.  I 
previously went through GDB's source code and replaced every occurance 
of STREQ* that is covered(1) by GDB's testsuite (or was in #ifdef 0 
code).  Since the before/after results were identical, I'm pretty sure 
those changes were ok.

Unfortunatly that still leaves GDB containing a notable number of STREQ 
references:
   49 ada-lang.c
    8 xcoffread.c
    7 coffread.c
    7 mdebugread.c
    6 dbxread.c
    6 rs6000-nat.c
    5 p-typeprint.c
    4 language.c
    4 mipsread.c
    3 dwarfread.c
    3 mcore-rom.c
    2 dwarf2read.c
    2 eval.c
    2 exec.c
    2 f-lang.c
    2 hpread.c
    2 source.c
    1 environ.c
    1 hppa-tdep.c
    1 objfiles.c
    1 p-valprint.c
    1 sparc-tdep.c
    1 stack.c
    1 target.c
While I could blindly transform those remaining references, such an 
operation would be untested and consequently runs the very real risk of 
introducing bugs (remember my test run didn't cover them).  Consequently 
they've been deprecated.

Per the weekend(2), they'll later be removed.

enjoy,
Andrew
