The sparc assembler under SunOS 3.2-Sys4 and SunOS 4.0 turn the line:
.common _line,280,"bss"
into a global symbol, hence it can not be used to allocate bss space
for local symbols.  There is a directive ".reserve" which will
accomplish this.

Repeat by:
compile the file:
---------------------------------------------------
static char line[200 + 80], *eptr = line, *lptr = line;
---------------------------------------------------

nm file.o will give:
00000000 d _eptr
00000008 C _line
00000004 d _lptr
instead of:
00000000 d _eptr
00000008 b _line
00000004 d _lptr

My fix:
