Search path for .lib and .include has been enhanced to read complete
...
or partial paths from environmental variables. The env variable
names have to start with '$' as the first character after the .inc
or .lib token. Two consecutive env variables are possible. They are
read each until directory separator '/' or '\\', or if none is found,
until the end of the line. In this case the filename has to be included
in the env variable. A .lib line may look like
.lib "$ENVS1\$ENVS2/libraries\sky130_fd_pr\latest\models\sky130.lib.spice" tt
If an env variable is read successfully, a ngspice variable with
the same name (without leading '$') and contents is defined for
use in a .control section.

"no" has channged to "yes". Some models with a look-up table defined

The lexer incorrectly treats a single '_' '-' '/' as an identifier. The counter used for tmp__ names should be incremented after use. The infix_to_postfix converter now has more checks for invalid infix expressions in LOGICEXP constructs. Without these checks the evaluation of the generated postfix could silently create bad gates which would load but simulate incorrectly. All MicroCap and PSpice libraries and QEI.cir pass their tests.

Several PSPICE 9.1 evaluation digital libraries contain timing .model statements at the global level for subckts with U* instances that reference those models. By specifying "set ps_global_tmodels=1" in .spiceinit an extra pass inside u_instances() will collect those global timing models for use in subckts. Report errors detected when ngspice parses a LOGICEXP but has not added support for operator precendence. Include a hint of how to fix those errors by inserting parentheses. This error only occurs in 10 of 585 cases in the libraries. Note that inpcompat.c has been saved as a unix filetype.
