Missing parentheses lead to build warnings
Although the build succeeds, the compiler raises warnings. I'll send a PR soon.

ch isn't 32bit, so this should be 'or ch, 80H'.

Since you are presumably not an alter ego of Agner Fog, you could disable these features on this repository.
Documentation contains incorrect letter case for some command-line parameters
"Instructions for objconv" file contains the following text:
-fXXX Convert file to format XXX. XXX = COFF, OMF, ELF or MAC.
PE is accepted as a synonym for COFF. The word size, 32 or 64, may be
appended to the name, e.g. ELF64
When I try to use command-line parameter -fOMF (case sensitive) I get an error "Error 2004: Unknown command line option: %sfOMF".
After some attempts I understand that it is correct to type "-fomf" (may be it is right only under Windows, I don't know).

Error 2052: Unexpected data between symbol table and string
I have fat binaries created with Xcode 5.1 for armv7 and armv7s (iOS 7.1).
After extracting object files with lipo and ar, if I try to use objconv on them I always get this error.
