I do it all the time.

Batch files are normally "sourced" by cmd.exe, and given the name of the
batch file you are dealing with, it sounds like it is modifying
environment variables for the VC toolchain.

Either translate vcvars32.bat to bash, or setup a .BAT file that
invokes both in sequence and then invoke that batch file from bash,
something like:

---vc---
#!/bin/sh
cmd /C MYVC.BAT $@
--------

---MYVC.BAT---
@ECHO OFF
VCVARS32
VC %1 %2 %3 %4 %5
--------------

It is possible to setup a "startup script" for a given instance
of CMD using a shortcut, which can then be placed in the program
files menu or on the taskbar.  Also, the System control has a
place to setup environment variables.
