When declaring uninitialized global data, the segments allocated to
store this data are the FAR_BSS segment for the compact, large, and
huge memory models and the C_COMMON segment for the small and medium
memory models. When the /Fa or /Fc compiler switches are used to
produce assembly listings from the C source code, the listing that is
generated actually has the segment incorrectly allocated as just _BSS.
Using the /Fm switch to generate a map file from the linker will show
that the segment is in fact FAR_BSS.
Microsoft has confirmed this to be a problem in C version 6.00. We are
researching this problem and will post new information here as it
becomes available.
