It looks like there might still something wrong (in 1.38). With my
(old) compilers I get:
with gcc 2.7.2.3:
gcc -c -I. -I. -I../include -I../include -g -O2 -Wall -fPIC -D__WINE__
-D_REENTRANT -I/usr/X11R6/include -o dpmi.o dpmi.c
dpmi.c: In function `DPMI_CallRMCBProc':
dpmi.c:254: fixed or forbidden register was spilled.
This may be due to a compiler bug or to impossible asm
statements or clauses.
and with egcs 2.91.66
g++ -x c -c -I. -I. -I../include -I../include -g
-O2 -Wall -fPIC -D__WINE__ -D_REENTRANT -I/usr/X11R6/include -o dpmi.o
dpmi.c
dpmi.c: In function `DPMI_CallRMCBProc':
dpmi.c:254: fixed or forbidden register 3 (bx) was spilled for class
GENERAL_REGS.
This may be due to a compiler bug or to impossible asm
statements or clauses.

The greatest programming project of all took six days; on the seventh day the
programmer rested. We've been trying to debug the *&^%$#@ thing ever since.
Resume: design before you implement.
