Version 2.12.02

Fix preprocessor errors, especially %error and %warning, inside %if statements.
Fix relative relocations in 32-bit Mach-O.
More Codeview debug format fixes.
If the MASM PTR keyword is encountered, issue a warning. This is much more \ 
likely to indicate a MASM-ism encountered in NASM than it is a valid label. This \ 
warning can be suppressed with -w-ptr, the [warning] directive (see section \ 
2.1.24) or by the macro definition %idefine ptr %??.
When an error or a warning comes from the expansion of a multi-line macro, \ 
display the file and line numbers for the expanded macros. Macros defined with \ 
.nolist do not get displayed.
Add macros ilog2fw() and ilog2cw() to the ifunc macro package.
