Compilation of the test programs revealed the following
(There were some other warnings, but much less important
or unimportant.)

* tests/libc/posix/fcntl/makef3gb.c
makef3gb.c: In function 'main':
makef3gb.c:44:47: warning: iteration 512000u invokes undefined
behavior [-Waggressive-loop-optimizations]
   for (i = 0; i <= BIGBUFSIZE; i++) bigbuf[i] = (char) i;
                                               ^
makef3gb.c:44:3: note: containing loop
   for (i = 0; i <= BIGBUFSIZE; i++) bigbuf[i] = (char) i;
   ^

Just fixed in makef3gb.c r1.2 by changing comparison from le to lt.


* include/math.h (sincos) :
In file included from strtold1.c:4:0:
../../../../include/math.h:261:8: warning: conflicting types for
built-in function 'sincos'
 void   sincos(double *_cos, double *_sin, double _x);
        ^
In file included from strtod1.c:4:0:
../../../../include/math.h:261:8: warning: conflicting types for
built-in function 'sincos'
 void   sincos(double *_cos, double *_sin, double _x);
        ^

My linux man page for sincos() has the prototype:
void sincos(double x, double *sin, double *cos);
The djgpp version has the parameters in reversed order.
The library compilation doesn't warn because the source
is in assembly not C. What to do with this?
