# Problem with \leq displaying as \leqslant

I assume it has something to do with my custom macro package, but I'm not really sure. I've just noticed that all of my \leq display as \leqslant the only thing that I could think would effect it is the beginning of my macro.sty:

\ProvidesPackage{macro}
\RequirePackage{amssymb,amsmath,amsthm,fancyhdr,mathabx}
\RequirePackage{graphicx}
\usepackage[top=.75 in,bottom=.75 in, left=.75 in, right= .75 in]{geometry}

But this all seems pretty harmless. I'm on Ubuntu 10.04, coding in emacs, compiling by pdflatex (pdfTeX 3.1415926-1.40.10-2.2) through auctex. I'll be happy to provide any more information, or the rest of my macro document if it would help. My headings are pretty generic:

\documentclass[12pt]{article}
\usepackage{macro}
